Portrait d'apparat—including objects associated with his subject's life in the portrait—was used by which artist? a. boucher b. watteau c. copley d. fragonard

I believe the correct answer is C. Copley.

Portrait d'apparat— a Rococo technique of portraying the subject with objects associated with him in his daily life—was used by American painter John Singleton Copley, whose portraits and historical subjects are generally acclaimed as the finest artist of colonial America. The use of Portrait d’apparat gave his works liveliness and acuity which was not usually associated with XVIII century American painting.
