Q2 Need help. Please explain

The image displays a graph with two polar curves: \( r = f(\theta) \) (solid line) and \( r = g(\theta) \) (dashed line). These curves are plotted in polar coordinates. 

Key Points on the Graph:
- Point \( A \) is located at \( \left[ 2, \frac{\pi}{2} \right] \).
- Point \( B \) is located at \( \left[ 5, \frac{\pi}{7} \right] \).
- Point \( C \) is located at \( [7, 0] \).

There is a shaded region between the two curves, and the task is to select the integral or integrals necessary to find the area of this shaded region.

Options for the Integral(s):

- \( \int_{2}^{\frac{\pi}{2}} \frac{1}{2} \left( [f(\theta)]^2 - [g(\theta)]^2 \right) \, d\theta \)
- \( \int_{5}^{2} \frac{1}{2} \left( [f(\theta)]^2 - [g(\theta)]^2 \right) \, d\theta \)
- \( \int_{2}^{\frac{\pi}{7}} \frac{1}{2} \left( [f(\theta)]^2 - [g(\theta)]^2 \right) \, d\theta \)
- \( \int_{2}^{5} \left( f(\theta) - g(\theta) \right) d\theta \)
- \( \int_{2}^{\frac{\pi}{2}} \frac{1}{2} [f(\theta)]^2 \, d\theta \)
- \( \int_{2}^{7} \left( f(\theta) - g(\theta) \right) d\theta \)

The graph visually guides how the polar curves intersect and enclose a region, which is significant for setting up the integral for evaluating the area.
