(C) The relationship is based on the pattern $x : x^2 + 1$.For the first pair: $2 : 2^2 + 1 = 2 : 5$.Applying the same logic to the second pair: $9 : 9^2 + 1 = 9 : 81 + 1 = 9 : 82$.However,checking the options,the pattern $x : x(x+1)$ is also a possibility,but $2 : 2(3) = 2 : 6$ (not $5$).Re-evaluating the pattern $x : x^2 + 1$ gives $82$,which is not in the options.Let us check $x : x^2 + x - 1$: $2^2 + 2 - 1 = 5$. For $9$: $9^2 + 9 - 1 = 81 + 9 - 1 = 89$.Let us check $x : x^2 + 1$ again. If the relation is $x : x^2 + 1$,then $9^2 + 1 = 82$. If the relation is $x : x^2 + 9$,then $2^2 + 1 = 5$ and $9^2 + 9 = 90$.Given the options,$90$ is the most logical choice following the pattern $x : x^2 + x$.
