C) 0.121 M

Explanation:

HCl + H₂O = H₃O⁺ + OH⁻

.121M. 121M

HCl is a strong acid. It will dissociate almost 100 % so the concentration of acid and hydronium ion formed will be equal. It is to be noted that hydronium ion is formed due to association of H⁺ and H₂O. H⁺ is formed due to ionisation of HCl.

So concentrtion of hydronium ion (H₃O⁺) will be. 121 M.
