Detailed explanation-1: -So, the wrong statement is ‘It helps in general plant metabolism’
Detailed explanation-2: -Abscisic acid (ABA) is an important phytohormone regulating plant growth, development, and stress responses.
Detailed explanation-3: -So abscisic acid induces dormancy in seeds, which prevents them from germination.
Detailed explanation-4: -Abscisic acid (ABA) is a phytohormone critical for plant growth and development and plays an important role in integrating various stress signals and controlling downstream stress responses. Plants have to adjust ABA levels constantly in responce to changing physiological and environmental conditions.
Detailed explanation-5: -Abscisic acid is also known as the stress hormone because it is found to induce various types of responses in plants against stress conditions like the closure of the stomata during drought, seed dormancy and it also ensures germination of seed during favorable conditions.
