Human resource management (HRM) plays a crucial role in any organization by overseeing the recruitment, selection, training, and development of employees. These functions are vital for ensuring that the organization has the right talent in place to meet its objectives and operate effectively. Furthermore, HRM is responsible for performance management, which involves assessing employee performance and providing feedback to help them grow and contribute to the organization. Additionally, managing employee relations is key to maintaining a positive workplace culture, resolving conflicts, and ensuring that employees feel valued and engaged.

While marketing and advertising, financial auditing, and product development are essential functions within a business, they are not part of human resource management. HRM focuses specifically on the management of people within the organization, which encompasses a wide range of activities that support workforce planning and development. Thus, the activities listed in the correct answer encapsulate the core responsibilities of human resource management, making it the right choice.
