Answer: A. His or her team's performance
Explanation: Usually, when being a team leader, a person is assigned to do some kind of task (depending on a company) along with his other colleagues. He is there to elaborate about the topic and make a decision on how it's going to be presented. Teammates are usually the ones that make suggestions about certain things that include the project. He is the one that represents the whole team and it all ''falls'' on his back if it doesn't go right.
