133 : 171

119 : 153

63 : 81

93 : 117

- Option 1: 133 : 171

- 133 and 171 are related as both numbers are one less than multiple of consecutive numbers, 133 = 11 x 12 +1, 171 = 13 x 14 -1.

- Option 2: 119 : 153

- 119 and 153 are both products of squares and cubes of consecutive numbers, 119 = 7 x 17, 153 = 9 x 17.

- Option 3: 63 : 81

- 63 and 81 are perfect powers, where 63 = 7^2-1 and 81 = 9^2.

- Option 4: 93 : 117

- 93 and 117 don't share these mathematical properties.

Option 4 is the odd one out because its number-pair doesn't share the similar arithmetic or factorial properties as the others.
