(S)-2-Phenyloxirane (styrene oxide) is opened in two ways: (i) with methanol containing a catalytic amount of $\mathrm{H}{}_2\mathrm{SO}{}_4$, where methanol attacks the carbon that best carries positive charge, with inversion there; (ii) with $\mathrm{CH}{}_3\mathrm{ONa}$ in methanol, where methoxide attacks the less hindered carbon. Which pair of major products is correct?

1. A(i) (S)-2-methoxy-1-phenylethan-1-ol; (ii) (R)-2-methoxy-2-phenylethan-1-ol
2. B(i) (R)-2-methoxy-2-phenylethan-1-ol; (ii) (S)-2-methoxy-1-phenylethan-1-ol
3. C(i) (S)-2-methoxy-2-phenylethan-1-ol; (ii) (S)-2-methoxy-1-phenylethan-1-ol
4. D(i) (R)-2-methoxy-2-phenylethan-1-ol; (ii) (R)-2-methoxy-1-phenylethan-1-ol
