View answer and explanation
Correct option: D
No Sodium gates in the egg membrane getting closed
Option D (No Sodium gates in the egg membrane getting closed) is correct because the closure of sodium channels is not a direct mechanism to prevent polyspermy. The fast block to polyspermy involves electrical changes due to influx of sodium ions, but the long-term block involves the cortical reaction and zona reaction.
