Correct Answer: 37 – 4

Solution : Let's check the options –
First option: 14 – 12→14 × 12 = 168
Second option: 24 – 7 →24 × 7 = 168
Third option: 42 – 4→42 × 4 = 168
Fourth option: 37 – 4→37 × 4 = 148 ≠ 168

So, the fourth option differs from the other three options as the product of the first and second numbers is 148 instead of 168. Hence, the fourth option is correct.
