Question

charcoal means the charcoal is porous and has a large surface area that can absorb and store large quantities of fuel vapor.

a. canister
b. activated
c. purging
d. evaporative

Explanation:

Activated charcoal has a porous structure which gives it a large surface area. This property allows it to adsorb (a process similar to absorption but with a different mechanism at the molecular level) and store large quantities of substances like fuel vapor. Canister is a container, purging is an action of removing something (like air from a system), and evaporative relates to evaporation. None of these other terms describe the property of the charcoal having a porous structure for adsorption as accurately as "activated".

Answer:

B. Activated
