Select the most appropriate option to fill in the blank.

The incident made a ______ impression on Karan.

deep

The most appropriate option to fill in the blank is deep.

The word "deep" means "having or showing a great understanding or insight." It is the most accurate word to describe the impression that the incident made on Karan.

The other options are incorrect.

• Factual means "based on facts." It is not the correct word to use in this sentence because the incident is not based on facts, it is based on Karan's experience.
• Rounded means "having a full and complete understanding of something." It is not the correct word to use in this sentence because Karan does not have a full and complete understanding of the incident, he just has a deep impression of it.
• Perfect means "without any flaws or defects." It is not the correct word to use in this sentence because the impression that the incident made on Karan is not perfect, it is just deep.
