(A) This is a NAND gate (B) if A = 0, B = 0 then Y = 1 (C) if A = 0, B = 1 then Y = 0 (D) if A = 1, B = 0 then Y = 1 (E) if A = 1, B = 1 then Y = 1 Choose the correct answer from the options given below:

(A), (D) and (E) only (D) and (E) only (B) and (C) only  (A) and (B) only

(B) and (C) only

This is a NOR GATE. For NOR Gate output is 1 only if both X and Y is zero. In all other case Output will be 1. Hence only B and C are true.
