Solution

The correct option is D forward, reverse
The emitter base junction is forward biased while collector base junction is reversed biased for the transistor to be working in the active state. As the first junction is forwardly biased, majority carries the current and goes to base but to reach the collector the second junction has to be reversed biased.
