"WebStep 2: Explanation of option ‘ (A)’. Spiny leaves do not increase the rate of transpiration in plants. Instead, these spiny leaves lower the transpiration rate. These spines possess thick cuticles and reduced surface area, and hence the rate of transpiration reduces significantly. Thus, spiny leaves do not increase transpiration.
