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)

The correct answer is D (which refers to part C containing the error, as option D represents the section containing the non-parallel structure "enhancing customer satisfaction").

Detailed Explanation:

To identify the error in the given sentence, let us analyze its grammatical structure and look for parallel construction:

1. The sentence presents a list of three infinitive goals connected by the coordinating conjunction "and":

• Goal 1: to expand its market share (infinitive structure: to + verb)

• Goal 2: increase profitability (bare infinitive structure: [to] increase)

• Goal 3: enhancing customer satisfaction (gerund structure: verb + -ing)

2. According to the rule of parallelism in English grammar, items in a list linked by conjunctions must take the same grammatical form. Since the first two items use infinitive verbs ([to] expand and [to] increase), the third item must also follow the same infinitive structure instead of using a gerund (enhancing).

3. Therefore, "enhancing" should be changed to "enhance" (or "to enhance") to maintain parallel structure:

"The company's goals are to expand its market share, increase profitability, and enhance customer satisfaction."

Thus, part (C) / Option D contains the grammatical error.
