Final answer:
Clear communication, trust and respect, and collaboration are essential for successful teamwork, while individual competition within a team can be counterproductive.
Step-by-step explanation:
Among the options given for elements essential for successful teamwork, clear communication is indispensable. Trust and respect are also fundamental, as they build the foundation for a collaborative environment and help prevent and manage conflicts. Meanwhile, collaboration is at the core of what makes teamwork effective, allowing the pooling and constructive use of various skills and perspectives. On the contrary, individual competition within a team setting can be counterproductive to the team's unified success and is not an essential element of successful teamwork.
For instance, when operating long-distance collaborations, the use of secure platforms for communication and a shared understanding of expectations around modes of communication are critical. Clear and jargon-free communication, understanding each other's priorities, and setting clear expectations are all essential practices to ensure success in team endeavors.
