A pendulum bob is kept at rest by a horizontal force $H$. The three forces acting on the bob are illustrated in the diagram. The tension in the pendulum string is $T$. The weight of the pendulum bob is $W$. Which of the following statements is correct?
- A$H = T \cos 30^\circ$
- B$T = H \sin 30^\circ$
- C$W = T \cos 30^\circ$
- D$W = T \sin 30^\circ$
