We can answer this question by looking for each of these acids and their dissociation property.
H₂SO₄ is sulfuric acid. Its Ka constant in high, it is in the order of thousands, which means it dissociates in water almost completely, so it is a strong acid.
H₂CO₃ is carbonic acid. Its Ka is very low, in the order of 10⁻⁷, so its makes an equilibrium a so it is a weak acid.
HCHO₂ is formic acid, and just like the carbon acid, it has a low Ka, in the order of 10⁻³, which makes it a weak acid.
HNO₃ is nitric acid, it is more similar to the sulfuric acid, having a Ka in the tens order. So, it is a strong acid.
