The oxoacids of Group 17 have the general formula HXO_n, where X is a halogen and n can take on values from 1 through 4.Which of the following is true? A) As the oxidation number of X increases, the strength of the acid decreases. B) As the oxidation number of X increases, the oxidizing strength of the acid increases. C) Only the oxoacids with oxidation number +1 are strong acids. D) The oxoacids with oxidation number +1 are reducing agents. E) The oxoacids with oxidation number +7 are weak oxidizing agents.

As the oxidation number of the halogen (X) in the oxoacid increases, the acid's ability to act as an oxidizing agent also increases. This is because a higher oxidation state of the halogen means it is more eager to gain electrons to return to a lower, more stable state.
