[#1109] All inputs must be in ON position to have an output is known as
Correct Answer

(B) AND gate

Explanation

Solution: All inputs must be in ON position to have an output is known as AND gate. An AND gate is a logic gate having two or more inputs and a single output. An AND gate operates on logical multiplication rules. In this gate, if either of the inputs is low (0), then the output is also low. If all of the inputs are high (1), then the output will also be high.
