your answer should be D

Answer: Option D

Explanation:

The given statement is false based on the experiment because he made cow pox vaccine a better choice for immunity against small pox.

The small pox vaccine cannot be used for the vaccine against cow pox because it has high fatality rate and even if the person survives it can suffer from scarring and lingering.

So, giving attenuated form of small pox vaccine could be dangerous so it cannot be used for the production of cow pox vaccine.

Hence, option D is False.
