Solution

The correct answer is finite.

Key Points

• The cardinality of a fuzzy set refers to the number of elements in the fuzzy set.
• In a fuzzy set, the cardinality is defined as the sum of the membership values of all elements in the fuzzy set.
• Since the membership values range between 0 and 1, and there is a finite number of elements in the set, the cardinality of a fuzzy set is finite.
