During natural selection, which organisms are most likely to survive as the environment changes? O ones that can best adapt to and survive in the changed environment
ones that can adapt to the original environment
ones that are randomly selected for survival independent of the environment
ones that are randomly selected for survival in the changed environment

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."

could you show the options for the answers? : )
