The correct answer of the given question is C) As surface area increased, the dissolving time decreased.
Explanation:
- Since the students are asked to put the mint leaves in their mouth this causes an increase in the surface area.
- The surface area is the total area of anybody living or non-thing that is exposed to a certain activity.
- This increase is surface area contact of mint with mouth makes it dissolve at a less rate than usual.
