Answer:
HBr
Step-by-step explanation:
As per the given options, HBr could be considered the strongest acid and the strength of its bond that makes it the strongest acid. This acid is highly precarious and toxic in comparison to other acids. It is so strong that it can immediately disunite and concedes its protons in suspension later. It is also strong as it gets ionized completely in an aqueous solution and also due to the hydronium ions formation on suspension. The other compounds do not do so.
