The ability of soil to undergo deformation without cracking is called as _______________.

Correct option is A

Plasticity of soil refers to the ability of soil to undergo deformation under moist conditions without cracking.
· It is an important property for understanding how soil behaves under various conditions.
· Soils with high plasticity, typically those with more than 15% clay content, can be molded or shaped when wet and retain that shape until they dry.
· This property is crucial for various engineering applications, including construction and agricultural practices.
