Solution

The correct option is D Calcium carbonate
If the soil has pH less than 7, it means that soil is acidic in nature. Dinesh can make it neutral by using some basic chemical. Calcium carbonate (limestone) is basic in nature. It increases the pH of soil and helps to make it neutral. So, Dinesh should use basic chemical such as calcium carbonate to make the soil neutral.
