Below is a set of sentences, read and choose the CORRECT sentence in each set. Select one: a. A questionnaire was distributed to the participants. b. A questionnaires was distributed to the participants. c. A questionnaire was distribute to the participants

a. A questionnaire was distributed to the participants.

Explanation:

The correct sentence in the set is "A questionnaire was distributed to the participants." Options B and C are both incorrect because of grammatical errors in the sentences.

In a sentence, 'a' is used to address a singular noun. Whenever there is a plural word, using the word 'a' to address the plural noun is incorrect. For instance, 'a questionnaire' is correct while 'a questionnaires' is incorrect.

Option C is also incorrect because after the word 'was', the word 'distributed' should have been used and not 'distribute' because the sentence is in simple past tense.
