Best answer
Correct option is (b) Sodium Hypochlorite

To elaborate: Sodium Hypochlorite acts like a bleaching agent. When it is dissolved in water and used to clean the labs, it gives off nascent oxygen. This oxygen is highly reactive and dangerous to microbes. It destroys the microbes that may have grown in the lab. It also helps remove stains due to its reactive nature and thus reduces/destroys the environment for microbes to breed.
