A simple pendulum of length \( l \) and bob of mass \( m \) is displaced from its equilibrium position \( O \) to a position \( P \) so that height of \( P \) above \( \mathrm{O} \) is \( h \). It is then released. What is the tension in the string when the bob passes through the equilibrium position \( O \) ? Neglect friction, \( v \) is the velocity of the bob at \( O \).
(A) \( m\left(g+\frac{v^{2}}{l}\right) \)
(B) \( \frac{2 m g h}{l} \)
(C) \( m g\left(1+\frac{h}{l}\right) \)
(D) \( m g\left(1+\frac{2 h}{l}\right) \)
