The process of storing tissues, organs, embryos and seeds at ______ is known as cryopreservation.

Solution
The correct option is D −196∘C
Conservation of biodiversity has become a global concern since the rate of biodiversity loss in recent times has become high. The approach of conserving threatened and endangered species of plants and animals by taking them out of their natural habitat and protecting them in a special and controlled environment is known as ex situ conservation.
Cryopreservation is the process of preserving living cells, tissues, organs or any biological construct indefinitely at a very low temperature of -196°C to protect them from any damage caused due to ageing or microbial decay. Hence option d is correct.
At such low temperatures, all enzymatic or chemical activities of a living cell remain suspended. Cryopreservation uses mechanised controlled freezing which prevents intracellular or extracellular ice formation, which can happen in regular refrigeration processes. Thus, damage to the cells is prevented.
Tissues, organs, embryos and seeds of threatened (vulnerable to endangerment in the near future) and endangered (seriously at risk of extinction) species can be conserved using this technique. It serves as an ex situ (off site) conservation strategy for bioresources.
