Detailed Solution

In forward biasing of PN junction current flows due to diffusion of majority charge carriers. While in reverse biasing current flows due to drifting of minority charge carriers. The circuit given in the reason is a PNP transistor having emitter more negative w.r.t. base so it is reverse biased and collector is more positive w.r.t. base so it is forward biased.
