From, sentence 1 and 2, we can see the code of great is “xj”.

In option (A), we don’t know the exact code of “some”, “school” and “good”, hence this cannot be our answer.
In option (B), we know the exact code of kapil, hence school can be find out.
In option (c), we know the code of “are” (from sentence 2 and 4), “great” and “all”, hence, we can find the code of school.

In this, we can find the code of “might be” from the sentence 1 and 3, hence, either “mk” or “vs” is our answer.

From, sentence 2 and 4, we can find the code of “qu” i.e. “are”.

From, sentence 1, 2 and 3, we can find “might be great”, and “science” is not given in the sentence above. Hence, “ms” is a new required code that is given in the option (E).
