Calcium carbonate is most likely to dissolve in water with:

e. Lots of Carbon dioxide and colder temperature.

Explanation:

Calcium carbonate is very sparingly soluble in water. However, it has been observed to dissolve in cold water with higher concentration of Carbon dioxide. The reason behind the observation is the formation of Calcium bicarbonate which is soluble in water. Higher concentration of Carbon dioxide in water turns it acidic. When this acidic water reacts with calcium carbonate it forms Calcium bicarbonate which is soluble in water. So, Calcium carbonate is most likely to dissolve in water with lots of Carbon dioxide and colder temperature.
