Here for proper operation is mentioned, that means BJT should work as an amplifier and it means BJT should be in (active region), for this junction between base & emitter i.e., emitter junction is FB and junction between base & collector i.e. collector junction (Jc) is RB. Saying base-emitter voltage FB means 'Vbe' is positive. i.e., it's NPN transistor, so in NPN transistor, the collector is positive and the base is negative to make it RB, so the answer is collector-base junction is to be reverse biased.

If the transistor is in the C-E mode?

If the answer is D then the question where base-emitter should change to emitter-base.
Because base-collector is the same as collector-base.
Because base-collector is the same as collector-base.

Here, the question refers to pnp bjt transistor, since it is given that the BE is forward biased, then the Base collector should be reversed biased for it to operate properly.
