A
Current due to majority charge carriers (both electrons and holes).
B
Current due to minority charge carriers (both electrons and holes).
C
Current due to majority and minority charge carriers.
D
Current due to majority and minority charge carriers (only holes).
Correct Answer
Option B
Detailed Explanation
In an unbiased PN junction diode current flow due to minority charge carriers (electron in the P-region and holes in the N-region).
