Base is more heavily doped than the collector
A.
Both the emitter and the collector are equally doped
B.
The base is made very thin and is lightly doped
C.
Collector is more heavily doped than the emitter
D.
Doping is a mechanism of increasing the conductivity of any metal by adding impurities.
The emitter in a transistor provides the maximum charge carriers for the flow of current. Thus it is heavily doped.
The collector collects the charges released by the emitter. Hence, it is made larger in size and is moderately doped.

The base of a transistor is helpful for the interaction between the emitter and the collector.
Thus the base passes the charge carriers released by the emitter to the collector. Hence, it is made very thin and is doped lightly.
