(C) The area bounded by the curve $y = f(x)$, the $x$-axis, and the lines $x = a$ and $x = b$ is given by the definite integral $\int_a^b y \, dx$.Here, $y = x^2 + 2$, $a = 1$, and $b = 2$.$	ext{Required Area} = \int_1^2 (x^2 + 2) \, dx$$= \left[ \frac{x^3}{3} + 2x ight]_1^2$$= \left( \frac{2^3}{3} + 2(2) ight) - \left( \frac{1^3}{3} + 2(1) ight)$$= \left( \frac{8}{3} + 4 ight) - \left( \frac{1}{3} + 2 ight)$$= \left( \frac{8 + 12}{3} ight) - \left( \frac{1 + 6}{3} ight)$$= \frac{20}{3} - \frac{7}{3}$$= \frac{13}{3} 	ext{ sq unit}$.
