The formula to calculate RDA for protein is body weight in kilograms multiplied by 0.8 grams of protein per kilogram. To convert Sarah's weight from pounds to kilograms, divide by 2.2: 178 ÷ 2.2 = 80.9 kg. Multiply that by 0.8 grams of protein per kilogram: 80.9 x 0.8 = 64.7 grams. Rounded to the nearest whole number, Sarah's RDA for protein is about 65 grams. Therefore, the best choice is C.
