• A. Hydrochasy
• B. Xerochasy
• C. Hydrotropism
• D. Chemotropism

Answer 1

The correct option is A Hydrochasy

Peristomal teeth of moss protrude out when the capsule is dry and curve when capsule is wet. Some plants survive droughts by curling up tightly until they become wet. Some wait to spend out seeds until they become wet. Hydrochasy is the technical term for plants that react to water by opening to disperse seeds

So, the correct answer is 'Hydrochasy'
