Which Nucleophilic Substitution Reaction Would Be Likely to Occur (Although $\rightarrow$

Which nucleophilic substitution reaction would be likely to occur (although probably not in excellent yield,due to competing elimination) ?

A) HO ^- + CH₃CH₂CH₂CHICH₃ $\rightarrow$ CH₃ CH₂CH₂CHOHCH₃ + I ^-
B) Cl ^- + CH₃CH₂CH₂CH₂-OH $\rightarrow$ CH₃CH₂CH₂CH₂-Cl + OH ^-
C) CH₃S ^- + CH₃CH₂CH₂-OCH₃ $\rightarrow$ CH₃S-CH₂CH₂CH₃ + OCH₃ ^-
D) All of the above are likely to occur
E) None of the above are likely to occur
