C: They redirect blood to the skeletal muscles.
D: They force the kidneys to retain salts.

The correct answer is option C

Epinephrine leads to constriction in blood vessels and causes dilation of blood vessels in the skeletal muscles and the liver. Also being a stress hormone it increases blood pressure, heart rate, and glucose from energy stores and produces constriction in the smooth muscles.
