Topic: Right Form of Verb,

Best Answer Explained in Below-:

The correct answer is option A) "participating in the country fairs," because it maintains the grammatical structure required by the original sentence. The phrase "look forward to" is a phrasal verb that is always followed by a gerund (the -ing form of a verb). This means that after "look forward to," we must use the gerund form of the verb to convey the intended meaning.

Let’s analyze why the other options are incorrect:

B) "participate in the country fairs" uses the base form of the verb ("participate"), which does not fit grammatically after "look forward to."

C) "be participating in the country fairs" introduces an auxiliary verb "be," which disrupts the required gerund structure.

D) "have participating in the country fairs" is grammatically jarring as "have" would signal a different construction, typically indicating possession or experience rather than anticipation, and likewise fails to use the gerund form appropriately.

In summary, option A is the only grammatically sound option, fulfilling the requirements of the phrase "look forward to" while clearly conveying the excitement farmers feel about country fairs every summer.
