did bought
A
Correct answer
Explanation
The phrase "last month" indicates a completed action in the past, so we use the simple past tense "bought". Present perfect "have bought" connects past to present and needs a time reference like "since" or "already". "Buyed" is misspelled - the past form of buy is "bought" (irregular verb). "Did bought" is grammatically incorrect because after "did" we use the base form "buy".
