What is the phase difference between the two points A and B on the following graph?

1. (A)\frac{7\pi}{4}\text{ radians}
2. (B)\frac{3\pi}{4}\text{ radians}
3. (C)\frac{3\pi}{2}\text{ radians}
4. (D)3\pi\text{ radians}

This question uses a figure or table from the paper — you'll see it when you practise.
