In one day, the person is in a calorie deficit of 1000 kcal (expending 3200 and consuming 2200). In a month, which is approximately 30 days, this deficit would accumulate to 30000 kcal (1000 kcal x 30 days).

Since 1 pound of body fat has an energy content of about 4100 kcal, the person would lose approximately 7.3 pounds of body fat (30000 kcal / 4100 kcal per pound). Therefore, the best choice is C) 7.3 pounds.
