Explanation:

Option (d)

To separate the suspended particles of clay from the water, alum is added in the loading tanks.

Chemically alum is a double salt of potassium and Aluminium sulphate, Hence called as potassium Aluminium sulphate.

The chemical formula for alum is $KAl(SO_{4})_{2}.12 H_{2}O$

Alum increases the rate of sedimentation of particles in water ( called as Loading) by following mechanism.

Alum is an external agent that causes the sparingly soluble particles to form colloids. This increase the weight of particles which leads to the formation of sediment at the bottom of the tank. The clear liquid can be decanted to separate liquid from suspended clay.
