Question

Choose the word or phrase that best completes the sentence.
Good morning, gentlemen. ______ one of you is first in line?
a- Which
b- Whose
c- Who
d- Whom

Answer 1

Hint: Interrogative words or ‘Wh’ words are used to indicate questions and relative clauses. The different ‘wh’ words are; whom, which, who, what, when, where, etc.

Complete answer:
Let’s look at the functions of different ‘wh’ words-
1) Which- ‘Which’ is used to indicate the specific thing or person out of the given choices. For example- Which car is yours?
2) Whose- ‘Whose’ is used to enquire about ownership. For example- Whose book is this?
3) Who- ‘Who’ acts as a subject in an interrogative sentence. It is used to ask questions about people. For example- Who is that girl?
4) Whom- ‘Whom’ acts like an object in an interrogative sentence. It is used to ask questions about people. For example- Whom should I contact?
In the given question- We can see the use of ‘one of you’, which means that there is a choice out of many gentlemen. Hence, ‘which’ is the correct option because it is used to ask about the particular person from the given choices.
Now, let’s examine the given options-
Option a- ‘Which’ is the correct option because we have been asked to indicate a choice.
Option b- ‘Whose’ is an incorrect option because we are not questioning about ownership.
Option c- ‘Who’ is an incorrect option because the sentence already has a subject.
Option d- ‘Whom’ is an incorrect option because the sentence already has an object.
The correct answer is Option ‘a’.

Note:
 Keep in mind, we use ‘which’ with non-defining clauses. Also, we usually use ‘which’ to enquire or ask questions about different things.
