A spherical body of mass $$m_1$$ moving with a speed $$u_1$$ collides elastically with a lighter spherical body of mass $$m_2$$ initially at rest. The maximum angle through which the heavier body gets deflected after collision depends upon

A

$$m_1$$ and $$u_1$$ only

B

$$m_2$$ and $$u_1$$ only

C

$$m_1$$ and $$m_2$$ only

D

$$m_1$$, $$m_2$$ and $$u_1$$ all
