How is that possible? Is that answer for the question 'disinfection of water with ozone is good because?'.

A is the correct answer. Ozone is a highly unstable oxidising agent so it does not remain in the water for a long time and it vanishes before the water reaches the consumers.

YES A IS THE CORRECT OPTION @Deepak.
Roy said:

A is correct. Ozone is very unstable.

I also marked the option A, as in chlorination residual chlorine is left in water so as to avoid any contamination during distribution.

Ozone O3 is unstable because it quickly releases the nascent oxygen (O) and becomes oxygen (O2) and escapes out of the water. So it is not possible to carry pure treated water up to the customer's outlet tap.
