A. 85 Percent

Explanation:

 The risk of head injury is decreased when wearing a helmet while riding a bicycle is 85%. This is because during the accident much amount of impact energy is consumed by the helmet instead of brain and head. Helmets create an additional layer for the head and in this way it protects the person from getting trauma injuries. Helmet aims to reduce the risk of getting severe head injuries.
