The correct answer is:
A

Cryopreservation is the technique of storing germplasm (seeds, tissues, cells, sperm, embryos, etc.) at ultra-low temperatures to preserve them for long periods.

Liquid nitrogen is used, which has a temperature of –196°C, ensuring metabolic activities stop and the germplasm remains viable for decades.
