Aluminum reacts slowly with dil. H₂SO₄ to produce:

C. Hydrogen gas

When aluminum reacts with dilute sulfuric acid (H₂SO₄), it undergoes a single displacement reaction. Here’s the balanced chemical equation for this reaction:

2Al(s) + 3H₂SO₄(aq) → 3H₂(g) + Al₂(SO₄)₃(aq)

As you can see, the reaction produces hydrogen gas (H₂) and aluminum sulfate (Al₂(SO₄)₃).
