    The electron concentration in an `` n `` -type semiconductor is the same as hole concentration in a `` p `` -type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them.
    (A)current in n-type = current in p-type
    (B)current in p-type > current in n-type
    (C)current in n-type > current in p-type
    (D)No current will flow in p-type, current will only flow in n-type
