b. 1440g-2080g/day

c. 321g-463g/day

d. 360g-520g/day

e. 142g-206g

Answer 1

Answer - (d.) 360 g - 520 g/day

The Eating guidelines for Americans recommends that carbohydrates make up to 45 to 65 % of your daily calories.

So here the man's energy requirement is 3200 k cal/day. that is 45 to 65 % of 3200 k cal/day is carbohydrate

45-65% of 3200 is 1440 - 2080 K cal /day is carbohydrate

Carbohydrate provide 4 calories per gram.

that is

1440 /4 = 360 grams/day

2080/4 = 520 grams/day

So the answer is 360-520 grams/day

the daily requirement of carbohydrate here is answer (d). 360 g-520 g/day
