i dont know yet

Explanation:

Perchloric acid is a strong oxoacid containing chlorine in its highest oxidation state (+7). Its chemical formula follows the naming convention for oxoacids where the "-peric" suffix corresponds to the highest oxidation state of the central halogen, paired with hydrogen and oxygen in the form $\text{HClO}_4$.

Answer:

$\boldsymbol{\text{HClO}_4}$ (Note: correcting a potential typo in the options, as the intended correct formula for perchloric acid is $\text{HClO}_4$; if the last option was meant to be $\text{HClO}_4$ instead of $\text{HNO}_4$, that is the correct choice)
