Verified by Toppr

Ethyl alcohol being a primary alcohol does not show a quick reaction (turbidity) with Lucas reagent.

All alcohols, though slightly acidic are, neutral to litmus.

Ethyl alcohol oxidizes to acetaldehyde, and thus gives a positive iodoform test.

Also, it gives an ester (fruity smell) with acetic acid.

Thus, these facts explain other statements.

Option D is correct.
