Correct answer & explanation

Master Data Management (MDM)
Master Data Management (MDM) is the discipline that creates a single authoritative view of customer data by identifying and merging duplicate records across systems. Option A is incorrect because Data governance focuses on policies and standards, not directly on merging records. Option B is incorrect because Data warehousing consolidates data for reporting and analysis, not for creating a golden record of master data. Option C is incorrect because Data quality ensures accuracy and consistency but is a component of MDM, not the specific discipline for managing master data.
