(C) The function is $y = |\sin 2x|$. We need to find the area bounded by this curve and the $X$-axis in the interval $[0, 2\pi]$.Since the period of $|\sin 2x|$ is $\frac{\pi}{2}$,the function repeats its shape every $\frac{\pi}{2}$ units.In the interval $[0, 2\pi]$,there are $4$ such identical humps (from $0$ to $\frac{\pi}{2}$,$\frac{\pi}{2}$ to $\pi$,$\pi$ to $\frac{3\pi}{2}$,and $\frac{3\pi}{2}$ to $2\pi$).Thus,the total area $A$ is given by:$A = \int_0^{2\pi} |\sin 2x| \, dx = 4 \int_0^{\frac{\pi}{2}} \sin 2x \, dx$$A = 4 \left[ \frac{-\cos 2x}{2} \right]_0^{\frac{\pi}{2}}$$A = -2 [\cos(2 \cdot \frac{\pi}{2}) - \cos(0)]$$A = -2 [\cos(\pi) - \cos(0)]$$A = -2 [-1 - 1] = -2 [-2] = 4$Therefore,the area is $4$ square units.
