Interrogative Pronouns

Interrogative pronouns are used to ask questions. They help us gather information about people, places, things, or time. In this question, we are asked to select the suitable interrogative pronoun to complete the sentence. Let's analyze the options given and determine the correct answer.

Options:
a) What
b) Whom
c) Whose
d) Who

Analysis:
In order to determine the suitable interrogative pronoun for the given question, we need to consider the context and the type of information we are seeking.

a) What:
"What" is used to ask about things or objects. For example, "What is your favorite color?" or "What is that?"

b) Whom:
"Whom" is used to ask about a person when it is the object of a verb or preposition. For example, "Whom did you meet?" or "With whom are you going to the party?"

c) Whose:
"Whose" is used to ask about possession or ownership. For example, "Whose book is this?" or "Whose car is parked outside?"

d) Who:
"Who" is used to ask about a person when it is the subject of a verb. For example, "Who is coming to the party?" or "Who is the best student in the class?"

Answer:
The correct answer is option b) Whom. In the given question, we are asking about the person or people we should visit on Sunday. Since the pronoun is the object of the verb "visit," we should use the interrogative pronoun "Whom." Therefore, the correct sentence would be "Whom should we visit on Sunday?"
