Why is it suitable to understand abscisic acid as both a growth inhibitor and a stress hormone?

Answer and explanation

Correct answer: Because it can inhibit growth and helps close stomata during water shortage

Abscisic acid, or ABA, is a plant hormone associated with growth inhibition and responses to environmental stress. During water shortage, ABA promotes stomatal closure, reducing transpiration and helping conserve water; it can also promote dormancy or suppress growth in suitable situations. It does not produce insulin, transmit animal nerve signals or control heartbeat. Therefore option A is correct.
