Correct answer and explanation

Correct answer: 865 : 722

Explanation: āœ… Correct Answer: A) 865 : 722 šŸ“š Explanation: Step 1: Check the numerical difference between the two numbers in option B: $378 - 255 = 123$. Step 2: Check the numerical difference in options C and D: $756 - 633 = 123$ and $967 - 844 = 123$. This establishes a consistent rule where the difference is always exactly 123. Step 3: Evaluate option A: $865 - 722 = 143$. Since this pair breaks the established pattern, it is the odd one out.
