B Correct answer
Explanation

A full wave rectifier requires a minimum of 2 diodes to convert both halves of the AC waveform to DC. In a center-tapped transformer configuration, two diodes conduct during alternate half-cycles. Bridge rectifiers use 4 diodes but that's not the minimum - the center-tapped design achieves it with just 2.
