Calculate the specific charge (\( e/m_e \) ratio) of an electron given that its charge is \( -1.602 \times 10^{-19} \text{ C} \) and its mass is \( 9.1094 \times 10^{-31} \text{ kg} \).

1. A
   \( 1.6022 \times 10^{-19} \text{ C kg}^{-1} \)
2. B
   \( 1.7588 \times 10^{11} \text{ C kg}^{-1} \)
3. C
   \( 9.1094 \times 10^{-31} \text{ C kg}^{-1} \)
4. D
   \( 1.7588 \times 10^{-11} \text{ C kg}^{-1} \)
