Answer :
Margaret's minimal protein needs, based on the RDA of 0.8 grams per kilogram of body weight for a sedentary adult, would be approximately 75 grams per day. The option (A) is correct.
To calculate Margaret's minimal protein needs, we must consider the Recommended Dietary Allowance (RDA) for protein. As per the RDA, a sedentary adult requires 0.8 grams of protein per kilogram of body weight per day. Converting Margaret's weight from pounds to kilograms (205 lbs / 2.2 lbs/kg), we get approximately 93.18 kg.
Multiplying her weight in kilograms by the RDA value (93.18 kg x 0.8 g/kg), we find that Margaret needs roughly 74.54 grams of protein per day. Therefore, the closest answer to Margaret's modest protein requirement would be 75 grams, which corresponds to option A.
