Final answer:
The module in an ERP system used to record marketing data is the Customer Relationship Management (CRM). It is where businesses compile data from various channels to understand customers' needs and improve business relationships.
Step-by-step explanation:
In an ERP system, the correct module used to record marketing data is often referred to as Customer Relationship Management (CRM). This module handles various aspects of a company’s interactions with current and potential customers, aiming to improve business relationships. CRM systems compile data from different communication channels, including a company’s website, telephone, email, live chat, marketing materials, and more. Through CRM, businesses can learn more about their target audiences and how to best cater to their needs, thereby promoting sales and customer retention.
While 'marketing' and 'customer service' are important aspects of an ERP system, they are distinct from CRM. 'Advertising' is a subset of marketing and is not typically a standalone module in ERP systems. Hence, the answer is C) customer relationship management.
