The correct answer is b) Stahl.

Explanation:

The cobalt chloride method is a technique used to demonstrate the process of transpiration in plants. Cobalt chloride paper is used to detect the presence of water vapor released during transpiration. When the plant is transpiring, the water vapor reacts with the cobalt chloride paper, changing its color from blue to pink.

This method was first used by Stahl, a scientist who contributed to early studies in plant physiology and transpiration.

Thus, the answer is b) Stahl.
