Truth functional connective meaning – UGC NET Question

A truth functional connective is defined by the way it systematically turns combinations of truth values of component statements into a truth value for the whole. For such connectives, once the truth values of the parts are known, the truth of the compound is completely determined. Examples include conjunction, disjunction, conditional and biconditional as studied in truth tables. Thus the connective described in the stem is properly called truth functional.

Option A:
Option A, intensional, usually refers to expressions whose meaning involves more than just extension or truth value, such as belief operators, and so is not restricted to connectives determined purely by truth values. Intensional contexts often break straightforward truth-functionality. Therefore intensional is not the correct label here.

Option B:
Option B is correct because truth functional connectives behave exactly as the stem describes: their semantic contribution can be fully represented in a truth table. This makes them central to classical propositional logic.

Option C:
Option C, non truth functional, would describe connectives or operators whose effect cannot be captured solely by reference to the truth values of component statements, which is the opposite of what the question states.

Option D:
Option D, analogical, has to do with reasoning by analogy between cases rather than with how connectives determine truth values. It is unrelated to the technical notion of truth-functionality.
