Suppression is the act of preventing or restraining something from being expressed or revealed. It can be done intentionally or unintentionally. In the given options, the opposite of suppression is "Encourage."

Explanation:
When we encourage something, we motivate and inspire it to grow and develop. We provide support and help to promote its growth. Encouragement can be in the form of words, actions, or gestures.

For instance, if someone is struggling with a particular task or problem, we can encourage them by providing helpful advice, acknowledging their efforts, and showing belief in their abilities. This kind of encouragement can help boost their confidence and help them overcome the difficulties they are facing.

On the other hand, suppressing someone or something can lead to negative outcomes. It can cause frustration, resentment, and even rebellion. For instance, if a person's creativity is suppressed, they may feel stifled and unable to express themselves, leading to a lack of motivation and productivity.

Conclusion:
In conclusion, suppression is an undesirable act, and the opposite of it is encouragement. Encouragement can help promote growth, productivity, and confidence in individuals. Thus, it is essential to encourage rather than suppress people and things around us.
