A dielectric slab having electric susceptibility \( \chi_e = 3 \) is placed in a uniform external electric field \( E_0 \). What is the ratio of the net electric field \( E \) inside the slab to the external field \( E_0 \)?

1. A
   \( \frac{1}{4} \)
2. B
   \( \frac{1}{3} \)
3. C
   \( \frac{3}{4} \)
4. D
   \( \frac{4}{3} \)
