A Correct answer
Explanation

In unisexual plants, sex expression can be modified by applying plant growth regulators, particularly auxins and ethylene. These hormones can influence the development of male or female flowers. For example, applying auxins or ethylene often promotes femaleness in certain species, while gibberellins may promote maleness.
