[amp_mcq option1=”bought” option2=”buy” option3=”have bought” option4=”will buy” correct=”option1″]
The correct answer is (A).
The sentence is in the past tense, so the verb must also be in the past tense. Of the four options, only “bought” is in the past tense.
“Buy” is the present tense form of the verb. “Have bought” is the present perfect tense form of the verb. “Will buy” is the future tense form of the verb.
In this case, the sentence is about something that happened in the past, so the past tense is the most appropriate tense to use.
