A) Constriction of most blood vessels
B) Increase of heart rate and force
C) Dilation of the vessels serving the skeletal muscles
D) Dilation of the blood vessels serving the skin and digestive viscera

*** I think its C since skeletal muscle isnt directly linked by the ANS.. What do you guys think?
