To cooperate with others is the correct answer because work together means to share effort, ideas, and responsibility with other people to complete a task.

This phrase is commonly used in group activities, classroom projects, games, and problem-solving tasks. It shows teamwork rather than one person doing everything alone.

Examples: We need to work together to finish the science project. The students worked together to solve the math problem.

The other choices are incorrect because to explain the meaning is about defining something, and to give the final answer is only one part of a task, not cooperation.
