The company’s new marketing campaign was a success, increasing sales by 20 percent, and boosting brand awareness. The team was thrilled with the results, noting that the campaign had been carefully planned and executed. Their success was due in part to their use of social media, which allowed them to reach a wider audience.

Which choice best combines the sentences at the underlined portion so that it conforms to the conventions of Standard English?
A. increasing sales by 20 percent, and boosting brand awareness and the team was thrilled with the results, noting that the campaign had been carefully planned and executed.
B. increasing sales by 20 percent and boosting brand awareness; the team was thrilled with the results, noting that the campaign had been carefully planned and executed.
C. increasing sales by 20 percent, boosting brand awareness, and the team was thrilled with the results, noting that the campaign had been carefully planned and executed.
D. increasing sales by 20 percent; boosting brand awareness, and the team was thrilled with the results, noting that the campaign had been carefully planned and executed.

Correct Answer is: C

The most effective way to combine the sentences is to use a comma after "awareness" and a comma after "results" to separate the two independent clauses. This creates a grammatically correct sentence with a smooth flow of information. Choice A is incorrect because it creates a run-on sentence. Choice B is incorrect because it uses a semicolon to separate two closely related independent clauses, which is not the correct punctuation. Choice D is incorrect because it uses a semicolon to separate two closely related independent clauses, which is not the correct punctuation.
