The correct answer is: liquid nitrogen
Semen is stored in semen banks for artificial insemination or artificial breeding, eg, Bull's semen is stored at $-196^{\circ} \mathrm{C}$ temperature. This temperature is obtained by liquid nitrogen.
Deep freezing is used for keeping seven day old embryos for several years. Deep freezing is also done at $-196^{\circ} \mathrm{C}$ (temperature of liquid nitrogen).
