Question

In the following sentence, fill in the blank with a verb in agreement with its subject.

The cost of all these articles _______ risen. [Advanced]

• A. Have
• B. Has
• C. Has been
• D. Are

Answer 1

The correct option is B Has

Has is used with a third singular person ("he", "she", "it", or a noun) i.e. when the subject is singular but it is neither the person who is writing/speaking ("I") or the person who's reading/listening ("you").

Haveis used for the third person plural. Example: They have a car.

Are is used when there are two or more things/names that are connected by 'and'. Has been is incorrect because the word following the blank is 'risen', and 'been risen' is incorrect grammatically.

So, the correct answer is option B) has.
