If a standard prescription includes 12 g of a medication and is to be taken three times daily, how many grams will be taken in one day?

To determine how many grams of medication will be taken in one day, we need to understand the total daily dosage based on the prescription. The prescription specifies that 12 grams of the medication is to be taken, and if this amount is taken three times a day, we calculate the total intake for that day.

The total daily intake is calculated by taking the amount prescribed per dose and multiplying it by the number of doses per day. In this case, the medication is prescribed as a total of 12 grams for the day (the full daily course), which is designated in the prescription.

Thus, the correct interpretation is that the patient will take the entire prescribed total of 12 grams throughout the day, fulfilling the prescription's requirement, rather than multiplying this total by the dosing frequency.

Each dosing schedule should clarify the total amount required for a specific timeframe. Since the prescription specifies 12 grams, the total amount consumed in one day remains 12 grams, confirming that option C is indeed the correct answer.
