Final answer:
The recommended daily protein intake for a sedentary adult male who weighs 87 kilograms is 58.0 grams.
Step-by-step explanation:
The recommended daily protein intake for a sedentary adult male is 0.8 grams of protein per kilogram of body weight (0.8g/kg).
To find the total grams of protein needed, multiply the weight of the adult male (87 kilograms) by the recommended protein intake per kilogram (0.8 grams/kg).
87 kilograms x 0.8 grams/kg = 69.6 grams of protein per day.
Therefore, the correct answer is B) 58.0 grams.
