No.

B, D, and E is not it. Then it should be C.

C. is right.

In this context, deep and profound are synonyms.

To determine the meaning of the word "deep" in the given context, we need to understand its role in describing the social satire in the books. In this case, "deep" suggests that the social satire included in the books was not superficial or superficially funny, but rather had profound or significant meaning.

To confirm our understanding and choose the correct answer, we can look at the options provided:
A. Buried - While "buried" might imply hidden or concealed, it does not capture the intended meaning of profound or significant social satire.
B. Rich - This option could be a possible answer as it suggests that the books had a wealth of social satire, but it does not explicitly convey the idea of it being profound.
C. Profound - This option is the most suitable because it directly relates to the intended meaning of "deep," suggesting that the social satire was significant or thought-provoking.
D. Tired - "Tired" does not align with the intended meaning of the sentence and is unrelated to the concept of deep social satire.
E. Low - "Low" does not convey the idea of profound or significant social satire.

Therefore, the correct answer is C. Profound.
