Solution

The correct option is B Sry gene - X chromosome
Testis-determining factor (TDF), also known as sex-determining region Y (SRY) protein, is a DNA-binding protein (also known as gene-regulatory protein/transcription factor) encoded by the SRY gene that is responsible for the initiation of male sex determination in humans.
So, the correct answer is 'Sry gene-C chromosome'.
