Correct Answer: Continual

Solution : The correct answer is the second option.

It is a suitable replacement for "habitual" because both words convey the idea of something that happens repeatedly or regularly. Habitual refers to behaviours or actions that are done as a matter of habit or custom, and continual refers to things that happen continuously or without interruption.

The meanings of other options are as follows:
