Which interrogative pronoun best completes the sentence? How is the pronoun used? __________ shirts are still drying on the clothesline? A. Whom; object of a preposition B. Whose; possessive C. Whom; direct object D. Who's; subject (in a contraction with a verb)

Respuesta :

The answer is B. Whose.

Because A. and C. don't make sense and D. is a contraction. If you used D. it would be like saying "Who is shirts are still drying?" and that doesn't make sense either.  

Whose is used because it is possessive. Your asking "Whose shirts?" The shirts are owned by someone.
