  2. B
    IAA and gibberellin
  3. C
    Auxin and cytokinin
  4. D
    Auxin and abscisic acid

Solution & Step-by-step Explanation

Morphogenesis in tissue culture is controlled by the ratio of Auxin and Cytokinin. High cytokinin-to-auxin ratio promotes shoot formation, while a high auxin-to-cytokinin ratio promotes root formation.
