I believe the answer is D because warm water generally has more nutrients than cold water.
It does not improve the nutrients so it isn't B or C.
Hope this helps!
The molarity of a solution if it tale 12.0 grams of Ca(No3)2 is calculated as below
molarity = moles/volume in liters
moles = mass/molar mass = 12.0 g/ 164 g/mol = 0.073 moles
molarity is therefore = 0.073/0.105 = 0.7 M
Answer is A bc you can get electrocuted
