The lack of competition within a monopoly means that

a. offered goods and services are lackluster.
b. the product’s market is small.
c. consumers must look elsewhere to find options.
d. prices are uniform and do not vary.

The answer is: D. prices are uniform and do not vary

In monopoly, the main producer of the product had the full power to influence the price in the market since there is no competitors that able to threaten its consumer base. This is why the price would be uniform.

On top of that, the producer in a monopoly also can afford to lower the quality of its product without having to worry its costumer would went away since the consumers would not have other options.

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."
