A 4 input AND gate is equivalent to

A 4 switches in parallel

B 2 switches in series and 2 in parallel

C three switches in parallel and one in series

D 4 switches in series

ANS:D - 4 switches in series

All the switches have to be closed so that the circuit can be made. In AND gate all the inputs have to be high for output to be high.
