OA is C
i think that "demand in..." sounds unidiomatic; this is not the case, however. the explanation states that because the demand is for the platinum, not the research, then it would be incorrect to say there is demand for research. im confused.

Meaning of the sentence

Platinum is scarce.
Demand for platinum is high in scientific research.
These are the reasons for platinum to be consistently expensive, like gold.

these are precisely expressed only in C. In other options, the phrase "the demand for scientific research" does not convey the intended meaning of the sentence.

Hope this helps.

The meaning of the sentence is : Platinum is not available and its demand in scientific research is increasing.

If you say :less availability and greater demand for scientific research.

Then it means the availability is less and some one is demanding scientific research . But that is not what the sentence is intending to say.
