We are comparing PLATINUM TO GOLD.

Remove the opening modifier to understand structure:

Platinum remains expensive, like gold. We can write it as "Like Gold, Platinum remains expensive".

When we use AS we mean literally
1) George behaves as a doctor = George is actually a doctor
2) George behaves like a doctor = George is not a doctor but behaving like one. We are taling about this 2nd usage in the your sentence.

If you look at all the options there are two differences between sentences, so you can split the answer into
C,E and A,B,D - Based on 'demand for' and 'demand in'. By now you would have figured out that 'demand in' is the correct usage in the senence.
Now out of C and E, you can eliminate E on two prefaces - 1st E is more wordy and not as concise(if you you feel difficult to rule it out on basis of comparison).
2nd, The element being compared is Platinum and not the price of platinum. Therefore, like gold is the correct usage.

I posted an explanation here:

Since LIKE is in all of the answer choices, the intended meaning must be that platinum is LIKE gold.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
