The correct answer is A.  

The victim was hit in the stomach and he might have bleeding that you can't see.  The shivering, dizziness, and "feeling funny" might be signs of shock.  Some of the first aid actions for shock have already been done.  A bystander phoned for help, and the victim is lying on his back.  You should now keep the victim warm.  If it does not hurt the victim to raise his feet, raise his legs about 12 inches.  

Answer b is incorrect because the victim has no signs of a heart attack and is responsive.  

Answer c is incorrect because you cannot stop bleeding you can't see with pressure, and pushing on his stomach may make the injury or the bleeding worse.  

Answer d is incorrect because you should not move a victim unless the area is not safe.
