Correct Option: A
Hairy roots are produced by infecting sterile plant with a natural genetic engineer, Agrobacterim rhizogenes. Genes for auxin synthesis and sensitivity are engineered into plant cells leading to gravity- insensitive mass root production. It is very useful for products produced in roots. Aggregation and shear sensitivity are a major problem for scale up.
