Square of the first number and adding 1 is equal to the second number

Let's check each option:

1) 9 : (9)2 + 1 ⇒ 9 : 81 + 1 ⇒ 9 : 82

2) 11 : (11)2 - 1 ⇒ 11 : 121 - 1 ⇒ 11 : 120

3) 5 : (5)2 + 1 ⇒ 5 : 25 + 1 ⇒ 5 : 26

4) 7 : (7)2 + 1 ⇒ 7 : 49 + 1 ⇒ 7 : 50

Hence, "11 : 120" is odd among the given alternatives.
