Study the given pattern carefully and select the number from the given options that can replace the question mark (?) in it.

​

Logic: The sum of the upper number's square = The sum of the lower numbers.

Upper Number: 2²+ 6² = 4 + 36 = 40

Lower number: 22 + 18 = 40

​According to figure number 2.

Upper Number: 5² + 2² = 25 + 4 = 29

Lower number: 17 + 12 = 29

​According to figure number 3.

Upper Number: 9²+ 3² = 81 + 9 = 90

Lower number: 65 + 25 = 90

Thus, the correct option is (c) 9.
