Correct Answer: Sporadic

Solution : The correct choice is the third option.

Sporadic means "occurring at irregular intervals or only in a few places or scattered or isolated" which means the opposite of incessant. Incessant means "continuing without pause or interruption".

The meanings of other options are as follows:

• Insistent: Persistent and demanding, characterised by a strong and unwavering emphasis or request.
• Daily: Occurring or recurring every day on a regular basis within a 24-hour period.
• Continual: Uninterrupted and ongoing, marked by consistent and frequent occurrences over time.
