21.
The Boolean expression for the circuit of the given figure
A {F + (B + C) (D + E)}
A [F + (B + C) (DE)]
A + F + (B + C) (D + E)]
A [F + (BC) (DE)]
Answer: Option
Explanation:

B and C in parallel give B + C. Similarly D and E in parallel give D + E. (B + C) in series with (D + E) give (B + C) (D + E). Since F is in parallel we get F + (B + C) (D + E). Finally A is in series. Therefore we get A[F + (B + C) (D + E)].
