Correct Answer: Definite

Solution : The correct choice is the second option.

The word certain is used to express a high degree of confidence, assurance, or clarity about something. It implies that there is no doubt or uncertainty. Similarly, the word definite conveys the same idea of clarity and certainty.

Both certain and definite are used to describe situations or information that are known for sure. They can often be used interchangeably to convey confidence and a lack of doubt.
