Reason: The author's argument in saying no to potassium supplements is based on the assumption that there are plenty of potassium rich food available in the market which can easily counter the effects of sodium.
Now, as per the OA if those foods contain an equivalent quantity of sodium then the countering effect of potassium will be nullified and therefore, potassium supplements will be needed to reduce the remaining sodium's effects.
I could not find a reason as to how Option C would be useful in evaluating the argument.

Hi mohit_1607,
For this CR question, you have to keep the FOCUS of the prompt in mind. The Focus is that consuming potassium reduces the harmful effects of sodium that is consumed. Make sure that the answer that you pick matches the Focus.
Answer C talks about DISADVANTAGES, which doesn't match the Focus.
Answer D talks about consuming potassium and sodium. That's an EXACT MATCH of the Focus. Thus, it's the correct answer.
