Solution

The correct option is B

Both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion


Both A and R are the correct statements.

Aluminum is a highly malleable metal but it cannot be used in particle scattering experiment as it is not thin enough.

Gold is most malleable, so it was used in particle scattering experiment as a very thin sheet of gold with around a 1000 molecules was needed to record the scattering of the alpha particles.
