The artist's latest exhibition, a vibrant collection of abstract paintings, (a) are (b) currently on display at the prestigious gallery, (c) attracting art enthusiasts (d) and (e) critics alike.
Correct: B
The subject of the sentence is "exhibition," which is singular. Therefore, the verb should be singular as well. "Is" is the correct singular form of the verb "to be" in the present tense. Thus, (B) is correct.
