(A) The potential at the $P$-terminal of the diode is $-4 \ V$ and the potential at the $N$-terminal is $-1 \ V$.Since the potential at the $P$-side $(-4 \ V)$ is lower than the potential at the $N$-side $(-1 \ V)$,the diode is in reverse-biased condition.In a reverse-biased state,an ideal diode acts as an open circuit,meaning it offers infinite resistance to the flow of current.Therefore,no current flows through the circuit,and the current is $0 \ A$.
