Choices

6

Choice-A

Choice A is incorrect. "Explaining" is a participle, not parallel with "provides" and "answers." Also, "clear" should be "clearly" to describe how the lesson is explained.

Wrong No change

7

Choice-B

Choice B is correct. This sentence uses consistent verb tense and form: "explains," "provides," "answers." "Clearly" is the correct adverb. The structure is fully parallel and correct.

Correct The teacher explains the lesson clearly, provides

8

Choice-C

Choice C is incorrect. "Explains" is present tense but "provided" is past, breaking parallel structure. All verbs must be in the same tense (present in this case).

Wrong The teacher explains the lesson clearly, provided

9

Choice-D

Choice D is incorrect. "Explain" is incorrect for a singular subject ("teacher"). It should be "explains." This creates subject-verb disagreement and breaks parallel structure.

Wrong The teacher explain the lesson clearly, provides
