Body \( A \) of mass \( 4 m \) moving with speed \( u \) collides with another body \( B \) of mass \( 2 m \) at rest. The collision is head-on and elastic in nature. After the collision, the fraction of energy lost by the colliding body \( A \) is
(a) \( \frac{8}{9} \)
(b) \( \frac{4}{9} \)
(c) \( \frac{5}{9} \)
(d) \( \frac{1}{9} \)
