__________ is a multidisciplinary field devoted to understanding individual and group behavior, interpersonal processes, and organizational dynamics.

A) Organizational behavior
B) Motivation
C) Performance management
D) Workgroup analysis
E) Accounting

Organizational behavior is specifically focused on understanding various dynamics of behavior within organizations, including individual and group behavior, as well as interpersonal processes. Motivation and performance management can be considered components of organizational behavior, but they are not comprehensive enough to describe the entire field. Workgroup analysis may touch on some aspects of organizational behavior, but it is not as comprehensive as the field as a whole. Accounting is not related to the study of behavior within organizations.
