Each question is divided into four parts where one of the parts may or may not contain an error. Choose the partthat has the error as your answer. If allthe parts are correct choose “No Error”.

The company's goals are (A)/ to expand its market share, (B)/ increase profitability, and (C)/ enhancing customer satisfaction. (D)

To identify the error in the sentence, we need to analyze its grammatical structure, specifically looking for parallel structure (parallelism) in the list of goals.

The sentence introduces a list of three goals for the company:
1. "to expand its market share" (infinitive phrase: to expand + object)
2. "increase profitability" (bare infinitive phrase: [to] increase + object)
3. "enhancing customer satisfaction" (gerund phrase: enhancing + object)

For a sentence to be grammatically correct and balanced, all items in a list must share the same grammatical form. Here, the first two items use infinitive verbs ("to expand" and "[to] increase"), while the third item shifts to a gerund ("enhancing").

To establish parallel structure, the third part should also use an infinitive verb form to match the others. Changing "enhancing" to "enhance" (or "to enhance") corrects the error:
"The company's goals are to expand its market share, increase profitability, and enhance customer satisfaction."

Since the error lies in the third goal, which is contained in part (D), the correct option pointing to the error is D.
