Answer: Option (a) is the correct answer.
Explanation:
A weak acid is defined as an acid that dissociates partially when dissolve in water or a polar solvent.
For example, acetic acid is a weak acid and when dissolved in water it dissociates partly into ions as follows.

And, a strong acid is defined as an acid which when dissolved in water dissociates completely into ions.
For example, HCl is a strong acid and when dissolved in water it dissociates completely.

Thus, we can conclude that the statement a weak acid solution consists of mostly non-ionized acid molecules, is true.
