(B) The circuit consists of switch $s_1$ in series with a parallel combination of $s_1'$ and $s_2'$,which is then in series with $s_2$.Symbolically,this is represented as $p \wedge (\sim p \vee \sim q) \wedge q$.Using the distributive law: $p \wedge ((\sim p \vee \sim q) \wedge q) = p \wedge ((\sim p \wedge q) \vee (\sim q \wedge q))$.Since $(\sim q \wedge q)$ is a contradiction $(F)$,we have $p \wedge ((\sim p \wedge q) \vee F) = p \wedge (\sim p \wedge q)$.By associative law: $(p \wedge \sim p) \wedge q = F \wedge q = F$.Since the symbolic form simplifies to a contradiction $(F)$,the lamp is always off.

If $p$: switch $s_1$ is closed,$q$: switch $s_2$ is closed,then the correct interpretation of the following circuit is:
