The Correct Option is...

✔ d. sol​

Explanation ⦂

Starch in water forms a colloid sol, when water is used to starch, it forms a lyophilic sol. When starch is mixed with water and heated, sols are formed at a rapid rate. Starch can be prepared by heating a solution of starch and water to 100 °C.

Starch has a stable nature, and is not affected by the presence of any electrolyte.

Sol is a colloid composed of very small solid particles in a continuous liquid medium. The nature of sol is permanent. Sol shows the Tyndall effect.

For example blood, paint, mud etc. The sol itself is used in making the sol-gel process.
