A technique of micropropagation is:

The correct option is C Somatic embryogenesis
Micropropagation is the practice of rapidly multiplying stock plant material to produce a large number of progeny plants, using modern plant tissue culture methods. And somatic embryogenesis is an in vitro process in which a plant or embryo is derived from a single somatic cell or group of somatic cells and these can be used for micropropagation.
Somatic hybridization is a technique which allows the manipulation of cellular genomes by protoplast fusion. Its major contribution to plant breeding is in overcoming common crossing barriers among plant species and in organelle genetics and breeding and not micropropagation.
