This is cellular totipotency property

The correct option is plants.

Cellular totipotency is the ability of a single cell to divide and produce all of the differentiated cells in an organism, ultimately giving rise to a whole new complete organism.
In biological systems, this property is most prominently and classically demonstrated in plants. Plant cells retain their totipotent character, allowing researchers to regenerate an entire plant from a single somatic cell (such as a leaf or stem cell) using tissue culture techniques.

While stem cells in animals can be pluripotent or multipotent (meaning they can differentiate into many or several cell types), they generally do not exhibit complete totipotency in the same easily regenerable manner as somatic plant cells. Viruses, being non-cellular entities that require a host machinery to replicate, do not possess cells or the property of cellular totipotency.
