Yes, the correct answer is D: blue cobalt chloride paper.
Transpiration is the loss of water by evaporation from the leaves through the stomata. A weight potometer measures the amount of water lost by a plant. However, the amount of water loss from a leaf can be detected using blue cobalt chloride paper.
