Correct option is
A

AMO-1618 and cyocel

Gibberellins are growth hormones. They stimulate cell elongation, thus help in plant growth. But certain commercial chemicals like AMO-1618 and cyocel are used to stunt growth. The chemicals inhibit the biosynthesis of gibberellin by blocking the pathway of gibberellin synthesis.
So, the correct answer is 'AMO-1618 and cyocel'.
