To calculate the amount of body fat a person would lose in a month, we need to first calculate the daily calorie deficit. The person is consuming 2,500 kcal per day and expending 3,500 kcal per day, meaning their daily calorie deficit is 1,000 kcal (3,500 - 2,500).

In a month's time, this adds up to a calorie deficit of 30,000 kcal (1,000 kcal x 30 days). We can now use the fact that 1 pound of body fat contains approximately 4,100 kcal to determine how much weight the person would lose.

30,000 kcal / 4,100 kcal per pound = 7.32 pounds.

Therefore, the person would lose approximately 7 pounds of body fat in a month. The correct answer is C.
