Question

In which sentence does the verb agree with the subject?

A.
The flowers' buds were a beautiful sight after a long winter.

B.
The strong smell in the kitchen are the onions.

C.
Peas has remained her favorite garden vegetable.

Answer 1

The correct answer is A. The flowers' buds were a beautiful sight after a long winter

It's not B because a strong smell is singular and then it requires Is instead of are, while it's not C because peas are a plural and require have remained instead of has remained.
