An OR gate has 6 inputs. The number of input words in its truth table are

Answer: Option C

A truth table shows all possible combinations of inputs and the corresponding output of a logic gate.

For a gate with 'n' inputs, the number of possible input combinations (or input words) is calculated as 2 raised to the power of n (2ⁿ).

In this case, the OR gate has 6 inputs.

So, the number of input words in its truth table is 2⁶ = 2 * 2 * 2 * 2 * 2 * 2 = 64.
