The correct order of strength of acids is given in option 1, which states that H2SO4>H3PO3>CH3COOH.

Let`s analyze each option to better understand why option 1 is correct:

Option 1: H2SO4>H3PO3>CH3COOH

This option correctly identifies sulfuric acid (H2SO4) as the strongest acid among the given options. Phosphorous acid (H3PO3) is weaker than sulfuric acid but stronger than acetic acid (CH3COOH).

Option 2: H2PO3>H3SO4>CH3COOH

This option is incorrect because sulfuric acid (H3SO4) is known to be stronger than phosphorous acid (H2PO3). Therefore, the order of strength is not accurately represented in this option.

Option 3: CH3COOH > H3PO3 > H2SO4

This option is incorrect because acetic acid (CH3COOH) is the weakest acid among the given options. Sulfuric acid (H2SO4) is known to be stronger than phosphorous acid (H3PO3). Therefore, the order of strength is not accurately represented in
