GA2
B
IAA

IPA
D
GA3
Explanation: 

Detailed explanation-1: -Gibberellin (GA3) plays an important role in the bolting of vegetables. GA3 can break dormancy and promote bud development [8].

Detailed explanation-2: -Gibberellins promote bolting in plants with rosette habit such as beet, cabbages, etc.

Detailed explanation-3: -Gibberellins are also involved in bolting, the rapid elongation of a (leafless) floral stalk that occurs naturally in many plants when they initiate flowering, example cabbage.

Detailed explanation-4: -Bolting is induced naturally under acceptable temperatures and by photoperiods which is when the plants receive the required amount of light or darkness. Bolting is induced artificially by treating with the plant hormone gibberellin which is naturally found in the plants but can also be exogenously produced.

Detailed explanation-5: -Gibberellic acid (GA), a plant hormone stimulating plant growth and development, is a tetracyclic di-terpenoid compound.
