C) had thrown

Question

Quizplus · Accepted Answer

The sentence is in past perfect tense, which indicates an action (throwing away photos) that occurred before another past action (realizing that he moved). Therefore, the correct helping verb is "had" and the correct past participle form of the verb "throw" is "thrown." Option A is incorrect because "throwed" is not a correct past participle form. Option B is incorrect because "has thrown" is present perfect tense, which does not match the rest of the sentence.
