The data in which of the following scatterplots would be best modeled by a quadratic function in which the $x^2$ term has a negative coefficient?

Choose the statement which consists of two correlated variables.

If $\displaystyle cov\left( X,Y \right) =1,var\left( X \right) =1,var\left( Y \right) =4$ then $Cor(X,Y)=$
