Final answer:

The Henderson-Hasselbalch equation can't be used in titrations of a strong acid with a strong base, a strong acid with a weak base, and a weak acid with a strong base. Correct option is a.

Step-by-step explanation:

The Henderson-Hasselbalch equation can't be used in the following cases:

  1. (a) Titration of a strong acid with a strong base
  2. (b) Titration of a strong acid with a weak base
  3. (d) Titration of a weak acid with a strong base

In these cases, the titration involves either a strong acid or a strong base, which means that the pH will not be influenced significantly by the dissociation of the acid or base.

The Henderson-Hasselbalch equation, which is based on equilibrium constants, is not applicable in situations where the acid or base is strong.
