In the given circuit, value of Y is
  1. (A)0✓ Correct
  2. (B)1
  3. (C)toggles between 0 and 1
  4. (D)will not execute

Answer: (A)

Solution

Following the connections from the inputs through the gates and reducing the resulting Boolean expression with De Morgan's rules, the function the circuit realises collapses to the product of a signal with its own complement, which is false for every input. The output therefore stays at logic .
