Yesterday my brother . . . . . . . . a car. A. purchases B. purchasing C. purchased D. purchase

The correct answer is C. purchased.

The verb “purchase” means to buy something. It is a transitive verb, which means it takes a direct object. In this case, the direct object is “a car.” The past tense of “purchase” is “purchased.”

The other options are incorrect because they are not the past tense of “purchase.”

• Option A, “purchases,” is the present tense of “purchase.”
• Option B, “purchasing,” is the present participle of “purchase.”
• Option D, “purchase,” is the infinitive of “purchase.”

I hope this helps!
