Comparative Strength of Acids

In the study of acids and bases, the strength of an acid is often determined by its ability to donate protons (H⁺). In a solution, different acids can have varying dissociation constants (K_a), which reflect their strength as acids.

Consider the following three acids, each with a different dissociation constant: Acetic acid (CH₃COOH) has a K_a of 1.8 x 10^-5, Hydrochloric acid (HCl) has a K_a of approximately 1.0 x 10⁷, and Carbonic acid (H₂CO₃) has a K_a for its first dissociation of approximately 4.3 x 10^-7. Based on these constants, which of the following statements is true regarding the strengths of these acids?
