Solution
The correct option is C Gibberellin, auxin and cytokinin
As gibberellins induce seed germination of light sensitive seeds like barley even in complete darkness, they are thus used to enhance malting in barley.
In pineapple spraying of certain auxins initiates uniform flowering in the whole crop.
Cytokinin production slows down the process of senescence and hence helps in the delay of leaf senescence.
So the correct answer is "option c".
