If the reference point of zero gravitational potential energy is chosen such that \( W(r \to \infty) = 0 \), the gravitational potential energy of a two-particle system with masses \( m_1 \) and \( m_2 \) separated by distance \( r \) is:

1. A
   \( \frac{G m_1 m_2}{r^2} \)
2. B
   \( -\frac{G m_1 m_2}{r} \)
3. C
   \( -\frac{G m_1 m_2}{r^2} \)
4. D
   \( \frac{G m_1 m_2}{r} \)
