Covariance is defined by the relation $\operatorname{Cov}(\mathrm{x}, \mathrm{y})=\langle\mathrm{xy}\rangle-\langle\mathrm{x}\rangle\langle\mathrm{y}\rangle$. Given the arbitrary constants A, B and $\mathrm{C}, \operatorname{Cov}(\mathrm{x}, \mathrm{y})$ will be zero if
(a)$\mathrm{y}=\mathrm{Ax}^{2}$
(b)$\mathrm{y}=\mathrm{Ax}^{2}+\mathrm{B}$
(c)$\mathrm{y}=\mathrm{Ax}+\mathrm{B}$
(d)$\mathrm{y}=\mathrm{Ax}^{2}+\mathrm{Bx}+\mathrm{c}$
