For the circuit show below, the Boolean polynomial is

  • ~ p  q  p  ~ q

  • ~ p  q  p  q

  • ~ p  ~ q  q  p

  • ~ p  q  p  ~ q


D.

~ p  q  p  ~ q

 Since, ~ p and q both switch also are in series ~ p  q            ...iand p and ~ q both switch also are in series p  ~ q           ...iiBoth Eqs. (i) and (ii) are parallel switch ~ p  q  p  ~ q

Hence, option (d) is correct.
