Read the given sentence to find out whether there is any error in any part and indicate your response.
Mr. Malhotra is a historian (A) who's books (B) have won international acclaim. (C) No error (D)

Correct option is B

· The error in the sentence is found in part (B), specifically with the use of the contraction "who's" instead of the possessive pronoun "whose."
· In this context, the correct word to use is "whose," which is the possessive form of "who." It is used to describe something belonging to or associated with a person. The contraction "who's" is incorrect as it is a contraction for "who is" or "who has," which does not fit the possessive need of the sentence.
· The corrected part (B) should read: "whose books."
Grammatical Rule:
· "Whose" is the possessive form of "who" and is used to attribute ownership or association to the subject referred to by "who." In contrast, "who's" is a contraction that should only be used when the meanings "who is" or "who has" are intended. Using "whose" correctly reflects possession in relation to "Mr. Malhotra" and his books, thereby maintaining grammatical accuracy and clarity in the sentence.
