Answer
NaOH is a strong base but is not commonly used for this conversion. HNO₃ is not typically involved in this reaction. Platinum (Pt) is a catalyst in some reactions but not for this specific conversion. H₂SO₄ (sulfuric acid) is known to effectively catalyze the dehydration of ethanol to ethene.
