A) $\bar{R}^{\prime}(x)=1.11-\frac{900}{x^{2}}$
B) $\bar{R}^{\prime}(x)=1.11-\frac{1000}{x^{2}}$
C) $\bar{R}^{\prime}(x)=0.001-\frac{900}{x^{2}}$
D) $\bar{R}^{\prime}(x)=0.001-\frac{1000}{x^{2}}$

The marginal average revenue is the derivative of the average revenue function. The average revenue function is $\bar{R}(x) = \frac{R(x)}{x}$. Differentiating $\bar{R}(x)$ with respect to $x$ gives $\bar{R}^{\prime}(x)=0.001-\frac{1000}{x^{2}}$.
