Which sentence correctly uses the word 'who' or 'whom'?
Correct: B
'Who' is a subject pronoun, and 'whom' is an object pronoun. 'Whom' is the correct choice when it is the object of a verb or preposition. In this case, 'whom' is the object of the preposition 'to'. Option 'Who did you say was coming?' is correct because 'who' is the subject of 'was coming'.
