This is the doctor . . . . . . wife is suffering from cancer. A. his B. whose C. whom D. a

The correct answer is: B. whose

The word “whose” is a relative pronoun that is used to refer to the possessor of something. In this case, the doctor’s wife is the possessor of the cancer.

The other options are incorrect because they do not refer to the possessor of the cancer.

• The word “his” is a possessive pronoun that is used to refer to a male person. In this case, the doctor is a male person, but the cancer is not his.
• The word “whom” is a relative pronoun that is used to refer to the object of a verb or preposition. In this case, the doctor’s wife is the object of the verb “is suffering.” However, “whom” is not used to refer to the possessor of something.
• The word “a” is an indefinite article that is used to refer to a general person or thing. In this case, the doctor’s wife is not a general person or thing. She is a specific person who is suffering from cancer.
