1. I gave my English class several alternative writing topics, none -they found motivating enough. (A) of whom BY whose of in which D) what which

The correct answer is (B) whose.<br /><br />Explanation:<br />The sentence is discussing the students in the English class, so we need a relative pronoun that can refer to people. The word "whose" is a relative pronoun that can be used to indicate possession or a relationship between the students and the writing topics. In this case, "whose" is referring to the students and their opinions about the writing topics.<br /><br />The other options are not correct:<br />(A) "of whom" is not a correct relative pronoun to use in this context.<br />(C) "of in which" is not a correct phrase to use in this context.<br />(D) "what" is not a relative pronoun and does not fit the sentence structure.<br />(E) "which" is a relative pronoun, but it is not the correct one to use in this context, as it does not indicate possession or a relationship between the students and the writing topics.<br /><br />Therefore, the correct answer is (B) whose.
