Answer»

Correct option is (c) Linguistic variables

For explanation: Linguistic variables are assigned non-numerical values to AID the representation of facts and rules. For example, a linguistic variable MAY take “hot” and “COLD” as input. In order to take advantage of the scale offered by fuzzy logic, additional words such as “RATHER” or “SOMEWHAT” may be used.
