Option D has the correctly spelt word. Secretarial means relating to the work or position of a secretary.

Let's understand the meanings of the given words:

Unsavory(घृणित) = unpleasant or morally offensive

Unsteady(अस्थिर) = not steady or firm; unstable; shaky

Unsafe(असुरक्षित) = not safe; at the risk of being harmed

Unsanctified(अपवित्र) = not holy because of being impure or defiled

The correct adjective for the sentence is "unsavory". It is because we are advised to stay away from the company of people who are morally unacceptable.
Hence, option A is the correct answer.

Let's understand the meaning of the given words:

Rancid(बासी) = smelling or tasting unpleasant as a result of being old and stale.

Carious(क्षयग्रस्त) = (of bones or teeth) decayed.

Putrid(सड़ा हुआ) = decaying or rotting and emitting a fetid smell.

Stale(बासी) = no longer fresh and pleasant to eat; hard, musty, or dry.

The question sentence quotes a time frame which means the activity of James teaching at the university started in June and it still continues. This means that the sentence should not be kept in the past tense. It should be kept in the present tense. Therefore, the use of "had been teaching" is incorrect in the sentence and should be replaced by "has been teaching". Hence, option A is the correct answer.

Also, the sentence shows a continuous activity which means the sentence should be of perfect progressive tense. So, part (C) would be incorrect. The subject "James" is singular, therefore, a plural verb would be incorrect here. So, option B is incorrect.

Let's understand the meaning of the given words:

Diligent(मेहनती) = having or showing care and conscientiousness in one's work or duties.

Assiduous(परिश्रमी) = showing great care and perseverance. So, it is the most suitable synonym.

Ridiculous(हास्यास्पद) = stupid or unreasonable and deserving to be laughed at.

Arduous(कठिन) = involving or requiring strenuous effort; difficult and tiring.

The idiom "backseat driver" refers to someone who gives unwanted advice or who tries to control something that is supposed to be controlled by another person.

Sentence Q talks about an ancient practice in India, i.e. the Sati system. Q should be followed by R as it shows data about the number of women who finished their life in this practice. The next sentence should be S as it shows the concern of the British against this system. Sentence P would be next as it mentions the reason why the British did not take any action against the Sati system. Hence, the correct sequence is QRSP.

Let's understand the meaning of the given words:

Reveal(प्रकट करना) = make (previously unknown or secret information) known to others.

Expose(प्रकट करना) = make accessible to some action or influence

Disclose(जाहिर करना) = uncover, expose to view

Veil(ढकना) = to obscure, or conceal with or as if with a veil

The idiom 'fight shy of" means to try to avoid something or someone.

The given sentence is in active form of simple past tense. The structures for active/passive voices are:
Active: Subject + verb (IInd form) + object...
Passive: Object + was/were + verb (IIIrd form) + by + subject...
In the active voice, the preposition “to” can be avoided as “presented” makes sense in itself. However, the passive voice requires the preposition “to” to indicate the recipient of the battle plan.
So, with the help of the above structures, we can convert the given sentence into passive voice: A detailed battle plan was presented to us by the General.
