Carbocations can be stabilized by resonance (e.g., allylic or benzylic carbocations), delocalizing the positive charge.

In SO₃ , sulfur is sp² hybridized with 3 equivalent bonds due to resonance, but bond angles are 120°. Adjusting for difficulty and options, SO₂ (119°) from prior sets suggests a misstep; SO₃ remains 120°. Correcting intent with options: NO₂ (~115° with radical) fits better if considered, but SO₃ is standard here.
