Question #148240

The correct sentence is: "He has eaten the pizza which he bought last night." This sentence is grammatically accurate and logically structured. It uses the present perfect tense "has eaten" to show that the action of eating the pizza was completed recently and may still have relevance now. The phrase "which he bought last night" is a relative clause that provides additional information about the pizza. The verb "bought" is correctly used in the past tense because the act of buying happened before the eating. This sentence shows the correct sequence of actions — first he bought the pizza, and then he ate it. Therefore, it follows proper tense usage and sentence structure, making it the best choice out of the given options.
