Answer:
Extrinsic semiconductor having a large number of current carriers would be (d) Electrically neutral.
Explanation:
It is because the n-type and p-type semiconductors have their own set of charge carriers and doping them enhances their conductivity, however, they are electrically neutral as the charges are balanced and in equilibrium.
An intrinsic semiconductor can be converted into an extrinsic one by doping it with either a trivalent or a pentavalent impurity.
