C Correct answer
Explanation

Liming is the application of calcium and magnesium rich materials to soil in various forms, including marl, chalk, limestone, or hydrated lime. This neutralises soil acidity and increases activity of soil bacteria. However, oversupply may result in harm to plant life. Lime is a basic chemical and  the effect of it makes the soil more basic, thus making acidic soils neutral.
