Solution

The correct option is D Skoog and Miller
Skoog and Miller first showed that organogenesis was governed by the balance of auxin and cytokinin in the tissue culture medium. Media with a relatively large auxin/cytokinin ratio induce roots, those with a low auxin/cytokinin ratio induce unorganized growth as callus tissue. Once induction occurs, it is followed by morphological differentiation and development.
