Step-by-step explanation:
The core topic in organizational behavior from the options provided is interpersonal communication. Organizational behavior is a field within business that studies how people interact within groups and how this affects the functioning of companies. A major part of this is understanding the social dimension of work, which includes topics such as management and leadership styles, organizational culture, and group dynamics that can influence performance and job satisfaction.
Interpersonal communication is critical for the smooth functioning of organizations as it directly influences how information is exchanged and acted upon, impacting decision-making, teamwork, and productivity. In contrast, quality improvement techniques, capacity issues, production processes, and statistical analysis might also play a role in the broader context of organizational effectiveness but are not primarily focused on the study of individuals and their behaviors within organizations.
