Perception distance + reaction distance + braking distance =
a. peripheral vision.
b. total stopping distance.
c. reaction time.
d. the distance from point a to point b.

option B) is correct

Explanation:

perception distance is the distance traveled by  the vehicle when the driver perceive the hazard situation.

reaction distance  is the distance traveled by the vehicle after seeing the hazard situation and reacting to it.

Braking Distance is the distance traveled by the vehicle after applying the brake.

so, the sum of Perception Distance + Reaction Distance + Braking Distance is called the total stopping distance

hence option B) is correct .
