Final answer:
The aqueous solution of HBrO4 is called perbromic acid, corresponding to the most oxygenated acid form of bromine, and is indicated by option (d).
Step-by-step explanation:
An aqueous solution of HBrO4 is named perbromic acid. When naming acids that consist of hydrogen and a halogen oxoanion, the names are formed based on the anion's name. Here 'per' signifies that it's the highest oxyacid for bromine (with the most oxygen atoms) and 'ic' indicates that it's an acid. Hence, HBrO4 is called perbromic acid, with HBr being hydrobromic acid and HBrO being hypobromous acid for comparison.
