The correct option is A Both the assertion and reason are true and the reason is the correct explanation of the assertion
Lipase enzyme is produced on an industrial scale which is used in detergent formulation. The enzyme breaks down oily stains on clothes. Surfactants in the detergent, then, attach to the remnants of the stain and remove it completely.
The use of lipases in detergents helps to minimise the use of phosphate-based chemicals in detergent formulations, and hence reduces environmental pollution along with enhancing the ability of the detergent to remove tough oil or grease stains.
