Select the most more appropriate option to fill in the blank.

The boy was rewarded for his ________ behaviour.

good

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

The word "good" is the most general and neutral term that can be used to describe positive behavior. It is not as specific as "correct" or "nice", but it is more appropriate in this context because it is not subjective. The boy's behavior was not necessarily pleasing or nice, but it was definitely good. He was rewarded for his positive behavior, not for his ability to please others or be nice.

The other options are not as appropriate because they are either too specific or too subjective.

• The word "pleasing" is too subjective. What one person finds pleasing, another person may not. It is not a good measure of good behavior.
• The word "correct" is too specific. It only applies to behavior that is in accordance with rules or standards. The boy's behavior may have been good, but it was not necessarily correct.
• The word "nice" is also too subjective. It is often used to describe behavior that is kind or thoughtful, but it can also be used to describe behavior that is simply pleasant or agreeable. The boy's behavior may have been nice, but it was not necessarily good.
