Correct answer: A
1. Analyze the first equation: 7 $ 3 = 58. The underlying pattern is squaring both numbers and adding them: 7² + 3² = 49 + 9 = 58. 2. Verify with the second equation: 6 $ 2 = 40. The pattern holds: 6² + 2² = 36 + 4 = 40. 3. Apply the confirmed pattern to the target equation: 5 $ 1 = 5² + 1². 4. Calculate the final result: 25 + 1 = 26. Final Answer: Option A
