AI Explanation

To answer this question, you need to understand the different terms related to examining data for statistics and information. Let's go through each option to understand why it is correct or incorrect:

It involves gathering statistics and information about the data, such as the number of missing values, distribution, data types, and patterns.

Option B) Data cleansing - This option is incorrect because data cleansing refers to the process of identifying and correcting or removing errors, inconsistencies, and inaccuracies in the data. While data cleansing may involve examining the data, it is specifically focused on improving data quality rather than gathering statistics and information.

It involves establishing policies, procedures, and standards for data management, including data quality, security, and compliance. While data governance may include aspects of examining data, it is a broader concept that encompasses various data management activities.
