D) somaclonal variation
Correct Answer: A
Solution :
Genetically improved varieties are those whose genome is altered artificially in laboratory by using different methods in order to favour the expression of desired physiological traits or for the production of desired biological products. Except cell suspension culture which is used for the multiplication of cells by providing them culture or by suspended them in a suitable medium. All three techniques given in the option i.e..
