The source of the pressure that has caused coyotes, which were once essentially diurnal, to adjust to a more nocturnal behavior is the presence of more aggressive diurnal predators, more commonly, lions. Lions only hunt in the day which limits the activity of the coyotes. As a result, the coyotes change their hunting schedules to nighttime to reduce competition.
Explanation:
Hunting Behavior. When existing in close closeness to humans, coyotes manage to be nighttime but may also be working in the early morning tide and at sunset. In cities with little or no human activity, coyotes will kill during the day, and when a scattering of pups demands to be fed, they may have to drive throughout the clock.

Well, we can rule out diffusion and osmosis because these are passive processes, so we're left with A and C. I'd say A, because the energy is used in muscle contraction.
