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