Which of the following statements is true regarding size of teams? a) the most effective teams have twelve to fifteen members. b) when teams have excess members, cohesiveness declines. c) as team size increases, social loafing decreases. d) when teams have excess members, mutual accountability increases. e) members of large teams coordinate work better when pressed for time.

The correct option is: B) When teams have excess members, cohesiveness declines

Explanation:

A team is defined as the group of individuals that work together to achieve a common desired goal. The members of a team are known as team members.

The composition and size of the team affects the outcome of the team. The optimal size of the team is considered to be between 5-12 members.

Also, homogeneity and the number of members in the group determines the cohesiveness of the group.

Therefore, if a group has excess team members, the cohesiveness of the group decreases.
