Answer 1

$\huge\bold{\mathbb{QUESTION}}$

The cost of all these articles $\sf \underline{\:\:\:\:\:\:\:\:\:\:}$ risen.

A. Have

B. Are

C. Were

D. Has

$\huge\bold{\mathbb{ANSWER}}$

The cost of all these articles $\sf \underline\bold{has}$ risen.

Correct option $\longrightarrow$

D. Has

$\huge\bold{\mathbb{REASON}}$

According to “Subject Verb-Aggrement”, a singular subject takes a singular verb and a plural subject takes a plural verb.

Here, “The cost of all these articles” is singular, because the main subject is “The cost”. Although the verb is after the word “articles" which is plural, it doesn't determine the number of subject. That's why, singular verb is used here.

“Has” is used here because the sentence is in present perfect.
