Answer:

c. dilated, constricted

Explanation:

During exercise, more energy is required by skeletal muscles. Oxygen is an important component required for energy production hence supply of oxygen is also increased to skeletal muscles. This is done by increasing the blood flow to skeletal muscles since red blood cells carry oxygen. To increase the blood flow, blood vessels in skeletal muscles are dilated so that more blood can reach them.

Blood vessels of digestive system are constricted because during exercise digestion process is not the priority. More blood should reach skeletal muscles than digestive system.
