Correct Answer: notorious

Solution : The correct choice is the second option.

Explanation:
"Notorious" specifically refers to someone who is well-known but for negative reasons, often associated with a bad reputation or infamy.

The meanings of the other options are as follows:

• An icon typically refers to a symbol or representation that is widely recognised and revered.
• Famous generally implies being well-known, but it doesn't inherently imply a negative reputation.
• Renowned signifies being widely acclaimed or honoured for positive qualities or achievements.

Therefore, the correct answer is notorious.
