JEE Main 2021 Physics question

For extrinsic semiconductors; when doping level is increased;

• (A)Fermi-level of p-type semiconductor will go upward and Fermi-level of n-type semiconductors will go downward.
• (B)Fermi-level of p-type semiconductors will go downward and Fermi-level of n-type semiconductor will go upward.Correct
• (C)Fermi-level of both p-type and n-type semiconductors will go upward for T > K and downward for T < K, where is Fermi temperature.
• (D)Fermi-level of p and n-type semiconductors will not be affected.
