Final answer:
The lowest level of task interdependence is a) Pooled interdependence, where tasks done by different team members are independent, and the overall outcome is just an accumulation of individual contributions.
Step-by-step explanation:
The lowest level of task interdependence is a) Pooled interdependence. In organizational behavior, task interdependence refers to the degree to which team members need to coordinate their work with other team members. Pooled interdependence is where the tasks are fairly independent, and the overall group performance is a sum of each individual's contributions. This differs significantly from other forms of interdependence, such as sequential interdependence, where tasks are done in a specific order, or reciprocal interdependence, which requires constant communication and back-and-forth between team members. Task interdependence is an essential concept for understanding how teams work and collaborate in an organizational setting.
