Ais an example of a service that can be purchased. a. car b. dvd c. sweater d. massage answer is : c

Is C your answer, or an answer given by a key? If it is yours, my advice is to rethink it.

If it is the key, argue a bit with your instructor/teacher.

A car is a thing. It has to be made.

A DVD is also manufactured.

A sweater using the same criteria as the first 2 is a thing that could be made by a machine, or by a very industrious knitter (someone who knits). 

The answer is D.
A Massage is given by a person who is very skilled. It is meant not only for relaxation, but to relieve pain. It is a service. Nothing is manufactured.

I would say C, because a massage is a service !

Idk why don’t you pay attention ok class
