Question

Choose the option that best corrects the statement at the underlined point:

One of his friend preferred to travel by air alone.

• A. NO CHANGE
• B. social circles
• C. colleagues
• D. acquaintance

Answer 1

Answer: (C)

colleagues

There are two numbers in Noun-Number: Singular and Plural. When we speak about one person / thing, we use the noun in singular form. When we speak about more than one person / thing, we use the noun in plural form.

In the sentence given, we are referring to one of many 'friends'. Hence, the underlined part must have a plural noun. Only options B and C are plural. However, social circles is a group of people and, hence, is not the correct option here.
This leaves us with option C as the right answer.
