In forward biasing of P N 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 P N P 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.
