Final answer:
The question lacks sufficient detail to give a precise answer regarding medication dosage. The importance of understanding unit conversions in medication dosing is highlighted.
Step-by-step explanation:
The question seems to be asking for the correct dosage range of medication for the entire body but lacks context for a specific answer. In the field of medicine, doses vary greatly based on the medication being used, the condition being treated, the patient body weight, age, and other factors. Therefore, without a specific medication and patient details, including body weight and age range, it's impossible to determine the correct choice among the options provided (A. 10 to 30, B. 30 to 60, C. 60 to 90, D. 90-120). Understanding the conversion of units is essential in prescribing the correct dose of medication. For instance, a healthcare professional should know how to convert milligrams (mg) to grams (g) when administering drugs. As explained with the aspirin example, 0.2 g equates to 200 mg, requiring the administration of four 50 mg tablets to achieve the needed dosage.
