Each of the following sentences in this section has a blank space and is followed by four choices. Select the most appropriate choice to fill in the blank.
Each of these paintings__________ made by a famous painter.

Correct option is B

The subject "Each of these paintings" is treated as singular despite referring to multiple items. The verb "is" therefore matches the singular subject according to subject-verb agreement rules in English grammar, which state that a singular subject must be paired with a singular verb.
