Topic: Right Form of Verb,

Best Answer Explained in Below-:

The correct answer is A) "shopping, doing" because it maintains grammatical parallelism and fits the context of the sentence. The sentence structure "I usually go --- or --- something else" requires gerunds, which are the -ing forms of verbs, after the verb "go." The phrase "go shopping" is a common expression meaning to engage in the activity of shopping, while "doing" follows the same gerund form.

Option B) "shopping, did" is incorrect because "did" is the past tense of "do," which disrupts the present-tense consistency of the sentence. Option C) "to shop, do" is also incorrect because it uses infinitive forms ("to shop" and "do"), which do not align with the sentence structure that implies ongoing activities rather than future intentions. Lastly, D) "shopping, do" mixes a gerund with an infinitive, creating an inconsistent structure that does not fit the context. Therefore, option A maintains the correct grammatical structure and tense consistency, making it the most appropriate choice.
