Quizplus · Accepted Answer

The sentence is in present perfect tense, which requires the helping verb "has" and the past participle form of the verb "know" which is "known". Therefore, the correct choice is "has known". Option A is incorrect because the subject "gardener" is singular and requires "has" instead of "have". Option C is incorrect because it does not have the correct past participle form of "know".
