Replace the given symbols and numbers in the options one by one with the original symbols and numbers in the given equation. Let's check the options – First option: 4 and 9, + and × 9 × 2 ÷ 7 × 8 + 4 = 25 = 9 × 2 ÷ 7 × 8 + 4 = 9 × 0.28 + 4 = 2.52 + 4 = 6.52 ≠ 25 Second option: 4 and 7, ÷ and × 7 + 2 × 4 + 8 ÷ 9 = 25 = 7 + 2 × 4 + 8 ÷ 9 = 7 + 8 + 0.89 = 15 + 0.89 = 15.89 ≠ 25 Third option: 4 and 9, ÷ and × 9 + 2 × 7 + 8 ÷ 4 = 25 = 9 + 2 × 7 + 8 ÷ 4 = 9 + 14 + 2 = 25 Fourth option: 4 and 7, + and × 7 × 2 ÷ 4 × 8 + 9 = 25 7 × 2 ÷ 4 × 8 + 9 = 7 × 0.5 × 8 + 9 = 28 + 9 = 37 ≠ 25
