If R = {red, blue, green}, what type of set is it?
Answer and explanation
Correct answer: Finite set
The set R explicitly lists three distinct elements: red, blue, and green. Since its members are limited and can be completely counted, R is a finite set with cardinality 3. It is not empty because it has members, and it is not infinite. A universal set can be identified only after a surrounding context is stated, so option A is correct.
