A technique of micropropagation is _________.

The correct option is A Somatic embryogenesis

• Somatic embryogenesis is the technique of raising somatic embryos in vitro by culturing somatic cells. The embryos derived from somatic cells are called somatic embryos.
• Embryo rescue is the technique of embryo development in vitro when the embryos are likely to get abort early.
• Somatic hybridization is the production of hybrid plants through the fusion of protoplasts of two different plant species or varieties.
• Since micropropagation is the clonal propagation using tissue culture, a technique of micropropagation is somatic embryogenesis in which somatic embryos are raised by culturing of somatic cells.

So, the correct answer is 'Somatic embryogenesis'.
