Which of the following is not an acronym related to marketing management?

The correct choice is C, HRM, because it stands for Human Resource Management, which deals with the management of people within an organization, focusing on hiring, training, and employee relations. While HRM is an essential area of business management, it does not pertain directly to marketing management.

In contrast, the other acronyms hold significant relevance to marketing. RFSM could represent Revenue Forecasting and Strategic Management, a concept tied to planning and evaluating marketing strategies to optimize revenue. MMS typically stands for Marketing Management System, which involves the systems and processes used to manage marketing activities and analyze data to improve effectiveness. SEM stands for Search Engine Marketing, which is a critical aspect of digital marketing involving the promotion of websites through paid advertising on search engines. Thus, HRM stands apart from these marketing-focused terms.
