This question tests understanding of alcohol reactions with HI. Primary alcohols (like CH₃CH₂OH) undergo S_N2 substitution to form alkyl iodides. Secondary/tertiary alcohols undergo S_N1 substitution. With Red P + HI, alcohols are reduced to alkanes. The correct option shows a primary alcohol (CH₃CH₂OH) reacting with HI alone to form the iodide (CH₃CH₂I), which is accurate.

Final answer: CH₃–CH₂–OH $\overset{HI}{\to}$ CH₃–CH₂–I
