A Correct answer
Explanation

Total profit = (Number of units sold) × (Selling price per unit) × (Profit percentage). Statement I gives quantity (12 mobiles), Statement II gives selling price (Rs. 15000 per unit), and the problem states profit is 25%. Statement III about purchase discount is irrelevant since profit percentage is already given. Statements I and II together are sufficient.
