Acidic strength depends on Ka value. The more the Ka is, stronger the acid is.
Hence option B is correct.

Answer: Option (B) is the correct answer.

Explanation:

When more effectively an acid is able to dissociate completely and give a proton or [tex]H^{+}[/tex] ion then it is known as acid strength.

For example, HCl is a strong acid and thus completely dissociates to give proton.

[tex]HCl \rightleftharpoons H^{+} + Cl^{-}[/tex]

Whereas [tex]K_{a}[/tex] is known as the acid dissociation constant. More is the value of [tex]K_{a}[/tex] more will be the acidic strength of acid.

Thus, we can conclude that when the [tex]K_{a}[/tex] increases, the acid strength increases best describes the relationship between acid strength and Ka value for weak acids.
