this means that those traits that are useful would be passed down, and non-useful traits would die out

The correct answer is c. Survival of the fittest.
Explanation: Survival of the fittest occurs when as the group of individuals of a particular species has the caracteristics or traits that allows them to be better suited or adapted to their local enviroment. The individuals of said species that lacks those specific characteristics usually goes extint.
In this case, the elephans that had long trunks with which to reach out for leaves were able to reproduce more succesfully than elephants with short trunks, which in turn went extinct.
In conclusion, the correct answer is C. Survival of the fittest.
a.) variation of species
b.) acquired inheritance
c.) survival of the fittest
c) Survival of the fittest
In Darwin's evolutionary theory, he described the process of natural selection whereby individuals with desirable that enables them adapt well to their environment, thrive well and reproduce more to leave behind more offspring with such characteristics than those with characteristics that are less favored by the environment. This struggle of survival as explained by Darwin is what can be referred as survival of the fittest.
The scenario illustrated in the question above is an example of the aspect of Darwin's theory that how "survival of the fittest" as a mechanism, ensures members of a population with traits that are favored by the environment reproduces successfully more than other individuals not favored through natural selection.
Long-trunked elephants will likely have a greater chance of survival compared to short-trunked elephants since they have the ability to reach their food better, therefore reproducing more long-trunked offsprings.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
