Soru: Choose the correct relative pronoun to complete the sentence: "The book ______ I borrowed from the library was very interesting."
A) who
B) which
C) whose
D) whom
Çözüm: The correct answer is B) which. We use "which" to refer to things. In this case, "which" refers to "the book". "Who" is used for people, "whose" shows possession, and "whom" is used as an object pronoun for people.
