Which of the following are mineral acids?

Mineral acids are acids produced from inorganic compounds. A hydrogen ion and a conjugate base are produced upon dissociation of a mineral acid. A carbon atom shouldn't be present in the conjugate base.

${\mathrm{H}}^{+}$ and ${\mathrm{NO}}_3^{-}$ ions are produced during the dissociation of nitric acid $\hspace{0.17em}\left({\mathrm{HNO}}_3\right)$. The conjugate base is ${\mathrm{NO}}_3^{-}$. Nitric acid is not an organic acid because it does not include carbon, making it a mineral acid instead. Thus, choice (A) is the right one.
Citrus acid $\left({\mathrm{C}}_6{\mathrm{H}}_8{\mathrm{O}}_7\right)$ is an organic acid rather than a mineral acid because upon dissociation, it produces a conjugate base that contains carbon. Option (B) is therefore untrue.
Since formic acid $\left(\mathrm{HCOOH}\right)$ dissociates into a base conjugate containing carbon, formic acid is an organic acid rather than a mineral acid. Option (C) is therefore untrue.${\mathrm{H}}^{+}$and ${\mathrm{Cl}}^{-}$ ions are produced during the dissociation of hydrochloric acid $\left(\mathrm{HCl}\right)$. The conjugate base is ${\mathrm{Cl}}^{-}$. Because it doesn't contain carbon, hydrochloric acid is a mineral acid rather than an organic one. So option (D) is correct as well.

Hence, the correct alternatives are options A and D.
