The correct option is C Clonal selection
Several varieties of clonal crops have been developed either by bud selection or by clonal selection from heterogeneous clones. Bud selection has been done in several fruit trees. For example, 'Bombay green banana' is considered to be a bud selection from 'Dwarf Cavendish'; 'Pidi Monthan' from 'Monthan', and 'High gate' from 'Gross Michel'. Thus, the correct answer is option C.
