In texas, the governor and legislative committee
a. have no role in planning the budget
b. work alone to plan the budget
c. work with the president to plan the budget
d. work with state agencies to plan the budget

the answer is c.Work with the president to plan the budget

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."

a would be the answer
