Where was most of the rice grown in royal georgia? a. on family farms near savannah b. on plantation farms near the coast c. on middle sized farms in the black country d. in corporate farms near augusta

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."
