Solution
The correct option is A Abscisic acid and Gibberellin
If two hormones have opposite actions on the plant body they are considered to be antagonistic.
Abscisic acid (ABA) is a plant growth inhibitor and plays a vital role in inhibiting plant metabolism and also induces seed dormancy under stressful conditions.
GAs are a group of growth hormone strongly associated with promoting growth, including stem elongation and seed germination. So ABA functions as an antagonist to Gibberellins.
