Which of the following statements is/are correct with reference to the whitest paint?

A. It was created by Engineers from Purdue University in the US.

B. It is made up of barium sulphate.

C. Both A & B

D. None of these

Explanation:

Engineers from Purdue University in the US have created what they are calling the whitest paint yet. Buildings coated with this paint may be able to cool them off enough to reduce the need for air conditioning. The team of researchers at the university created an ultra-white paint in October pushing the limits of how white paint can be. This older formulation was made of calcium carbonate, while the new one is made up of barium sulphate, which makes it more white. It is made up of barium sulphate.
