Two things:
1. Like that of:

When X's a is compared with Y's a, we use "like that of Y".
Example:
The price of rice remains constant, like of wheat.

In the sentence above, X has been compared with Y. In that case we are not required to use "like that of".
==> Eliminate B and E.

2. Demand for V s Demand in

"Demand for scientific research"means the demand is for research not for platinum. The intended meaning is "demand for platinum"; therefore, "demand for" changes the intended meaning of the sentence.

==> Eliminate A and D.

C, the best choice, wins.
