C Correct answer
Explanation

About 90% of water absorbed by herbaceous plants is lost through transpiration. This high loss is the trade-off for opening stomata for CO2 uptake during photosynthesis. The other percentages (80%, 60%, 40%) underestimate actual transpiration losses in most herbaceous plants.
