The section presents a chemistry problem related to strong acids. It asks which of the given options is the strongest acid. The options provided are:

A. Hydrochloric acid (HCl)  
B. Sulfuric acid (\( \mathrm{H}_{2} \mathrm{SO}_{4} \))  
C. Nitric acid (\( \mathrm{HNO}_{3} \))  
D. Carbonic acid (\( \mathrm{H}_{2} \mathrm{CO}_{3} \))  

The key topic is the comparison of the strength of different acids. The entities involved are the chemical formulas and names of the acids listed.
