Final answer:

The correct answer is option (C) type A blood.

Step-by-step explanation:

The blood type that contains only the A antigen is type A blood.

There are four main blood types: type A, type B, type AB, and type O. Type A blood has only the A antigen present on the surface of the red blood cells. This means that people with type A blood have antibodies against the B antigen in their plasma, which makes them unable to receive blood from individuals with type B or AB blood.

Therefore, the correct answer is type A blood.
