Enhancing and cleaning data is an important action during which phase of CPMAI?

CPMAI defines Phase III (Data Preparation / Engineering) as the stage where raw data is cleansed, enriched, transformed, and integrated to create an analysis-ready corpus for later modeling phases.

A. Phase VI concerns deployment/operations, not data cleaning.
B. Phase I focuses on business understanding.
C. Phase V is model evaluation.
E. Phase II is data understanding (profiling, quality assessment), not full cleaning.
F. Phase IV is model development.
