Which of the following is NOT one of the main phases of the data analytics lifecycle?

The correct choice is C, because data encryption is not considered one of the main phases of the data analytics lifecycle. The data analytics lifecycle generally encompasses several critical phases that are involved in transforming raw data into insightful analyses. These typically include data collection, where data is gathered from various sources; data processing, which involves cleaning and organizing this data; and data analysis, where analytical techniques are applied to extract meaningful insights.

Data encryption, while important for protecting sensitive information, is primarily a security measure and not a phase in the analytical process. It aims to secure data both at rest and in transit, ensuring that unauthorized access is prevented. However, it does not contribute to the transformation of data for analysis. Understanding these specific phases of the data analytics lifecycle is crucial for anyone involved in the field, as it helps to delineate the steps required to smoothly transition from data gathering to actionable insights.
