An n-p-n transistor conducts when (a)Both collector and emitter are negative with respect to the base. (b)Both collector and emitter are positive with respect to the base (c)Collector is positive and emitter is negative with respect to the base (d)Collector is positive and emitter is at same potential as the base.

(c)

When the collector is positive and emitter is negative W.r.t. base, it causes the forward biasing for each junction, which causes conduction of current.
