Question

Fill in the blanks with the correct pronoun.
shall I say is calling?
do you advice the most?

• A. whom / whom
• B. whom / who
• C. who / who
• D. who / whom

Hint:

Check whether the missing word is the subject or the object of the verb.

Answer 1

The Correct Option is D

This question tests the difference between "who" and "whom". "Who" acts as the subject of a verb, and "whom" acts as the object of a verb or preposition.

1. whom / whom: in the first sentence, the missing word is the subject of "is calling", so it must be "who", not "whom". This pair is wrong.
2. whom / who: the same problem applies to the first blank, and the second blank also needs "whom", since it is the object of the verb, not "who". Both halves are wrong.
3. who / who: the first blank is correct with "who", but the second blank needs "whom" because it stands for the person being asked about, the object of the verb, not the doer of the action.
4. who / whom: in "Who shall I say is calling", "who" is the subject of "is calling". In "Whom do you advice the most", "you" is the subject and the missing word is the object, so "whom" is right.

The two sentences test opposite roles: the first blank needs the doer of the action, and the second needs the receiver of the action, so the correct pair mixes "who" and "whom" rather than repeating the same word twice.

Let's summarize:

• Use "who" when the missing word performs the verb's action, like a subject.
• Use "whom" when the missing word receives the action, as the object of a verb.

The correct pair is "who" then "whom", which makes option (d) the right choice.
