Explanation
Correct answer: C.
Choice C is the best answer. The subject of the sentence is “The African Games Co-production Market.” That’s one market, so it’s a singular noun, which means it needs a singular verb. “Promotes” is the only singular verb among the choices.
Why the other choices are wrong
Choice A
Choice A is incorrect. This choice creates a subject-verb agreement error. The subject “The African Games Co-production Market” is singular, but the verb “promote” is plural.
Choice B
Choice B is incorrect. This choice creates a subject-verb agreement error. The subject “The African Games Co-production Market” is singular, but the verb “are promoting” is plural.
Choice D
Choice D is incorrect. This choice creates a subject-verb agreement error. The subject “The African Games Co-production Market” is singular, but the verb “have promoted” is plural.
