Q. Choose the correct alternative which replaces the given statement/sentence:
“Anything written in a letter after it is signed”.

The correct answer is: (C) Postscript

Explanation:

– A manuscript refers to a handwritten or typed document, especially a draft of a book or article, and is unrelated to the context of something written after a letter is signed.

– Postdiction refers to explaining or predicting an event after it has already occurred, which is not relevant to the context of a letter.

– A postscript (commonly abbreviated as “P.S.”) is an additional remark or message added at the end of a letter after the signature. This matches the description in the question.

– A corrigendum refers to a correction of an error in a published text, which is unrelated to the context of a letter.

Thus, the correct alternative is Postscript (C).
