Solution
The correct option is C Auxin and cytokinin
When a tissue with a potential of differentiation is grown in an artificial medium containing auxin and cytokinin in a specific ratio, it starts differentiating. Thus, root and shoot differentiation occurs. Auxin initiate root formation while cytokinin starts shoot formation.
Gibberellins are plant hormones that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, flower development, and leaf and fruit senescence.
IAA has many different effects, such as inducing cell elongation and cell division with all subsequent results for plant growth and development.
Abscisic acid (ABA) is the major hormone that controls plant's ability to survive in a harsh, changing environment.
