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 find the part of the sentence that contains an error, we need to analyze its grammatical structure, specifically looking for parallel structure (parallelism) in the list of goals.

Let's examine the structure of the list describing the company's goals:
1. "to expand its market share" (infinitive phrase: "to" + base verb "expand")
2. "increase profitability" (infinitive phrase with "to" understood: "[to] increase")
3. "and enhancing customer satisfaction" (gerund phrase: "enhancing" [verb+ing])

For a sentence to be grammatically correct and balanced, all items in a list must share the same grammatical form. This rule is known as parallel structure.
Here, the first two items are infinitive phrases ("to expand", "[to] increase"), while the third item shifts to a gerund ("enhancing").

To correct the error and maintain parallelism, the third item must also be in the infinitive form to match the others. It should be written as "enhance customer satisfaction" (with the "to" from the first item distributing to all parts of the list):
"The company's goals are to expand its market share, increase profitability, and enhance customer satisfaction."

Therefore, the error lies in part (D), which uses "enhancing" instead of "enhance".

The correct answer is Option D.
