To solve this problem, first convert the weight of the person from pounds to grams:
175 lb x 454 g/lb = 79,450 g

Next, calculate the total amount of calcium:
79,450 g x 15 mg/g = 1,191,750 mg

To convert the result to pounds, divide by the number of milligrams per pound:
1,191,750 mg / 453,592 mg/lb = 2.63 lb

Therefore, the answer is C, 2.63 lb.
