With whom should I pair up? Group ‘A’ Group ‘B’ (1) Air (a) Excretion (2) Water (b) Scattering of light (3) Soil (c) Plasticity

For 1 , The air is a homogeneous mixture of different gases and particles. A mixture in which the components are difficult to distinguish is a homogenous mixture. The particles present in the air cause the deflection of light rays from their straight path. This phenomenon is known as scattering of light. Answer - ( 1 ) matches (b).
