Suppose y varies as the sum of two quantities of which one varies directly as x and the other inversely as x. If y = 6 when x = 4 and y = $${\text{3}}\frac{{\text{1}}}{{\text{3}}}$$ when x = 3, then the relation between x and y is -

• A. $y = 2x - \frac{8}{x}$$
• B. $y = x + \frac{4}{x}$$
• C. $y = 2x + \frac{4}{x}$$
• D. $y = 2x + \frac{8}{x}$$
