✓ Answer: A Mg
Magnesium (Mg) is more active towards dilute hydrochloric acid. Magnesium is the most reactive among the mentioned metals and reacts vigorously with dilute hydrochloric acid, releasing hydrogen gas. Aluminum reacts with hydrochloric acid but forms a protective oxide layer that slows down the reaction. Zinc reacts moderately with hydrochloric acid.
