Final answer:
Among the provided options, Offering constructive feedback is the best way to show support and provide encouragement to teammates. It acknowledges their efforts and focuses on improvement, while maintaining a positive team environment.
Step-by-step explanation:
The actions that show support and provide encouragement to teammates are centered around positivity and enhancement of team morale. Among the provided options, Offering constructive feedback is the action that would contribute prudently to supporting and encouraging team members. Constructive feedback helps team members improve their skills and acknowledges their efforts, whereas the other options may lead to demotivation and decreased team cohesion. For example, approaching a peer's work fairly and free of personal bias, coupled with tactful and considerate suggestions, fosters a helpful environment. Celebrating a teammate’s accomplishments and providing opportunities that interest them are also practical ways to provide support.
Moreover, adopting a positive attitude and actively collaborating within a team amplifies the effectiveness of feedback. Openness to receiving feedback is equally important, as it lays the groundwork for continuous improvement and learning. An example in a different context, like a workplace, further underscores the value of a positive outlook and cooperation, as these traits are highly valued and contribute to better job performance assessments.
