In the following circuit the correct relation between output (Y) and inputs A and B will be

A NAND gate can be implemented using two diodes and a transistor, where the output Y is the inverse of the AND operation of inputs A and B (Y = NOT(AB)). When both inputs are low (0V), both diodes are forward-biased, creating a short circuit that keeps the transistor in cut-off state, resulting in Y = 1 (high). When either or both inputs are high (10V), the diodes become reverse-biased, allowing current to flow into the transistor base, saturating it and pulling Y to 0 (low). This circuit demonstrates how basic electronic components can be combined to create fundamental logic gates.
