Answer 1

Answer: (B)

A- r, B- s, C- t, D- p

Transpiration is the loss of water as water vapour from plant parts through stomata, whereas guttation is the loss of water as a liquid solution through hydathodes. Exudation is the loss of water from injured plant parts. Fermentation is anaerobic respiration. It occurs in organisms like yeast. Yeast convert sugars into alcohol through fermentation. Thus, the correct answer is option B.
