D Correct answer
Explanation

Building a data warehouse involves Requirement gathering, Data modeling, and Data profiling as core steps. Data mining is an analytical technique performed on data, not a step in building the warehouse infrastructure itself.

AI explanation

Data mining is correct — it's not a step in building a data warehouse but rather an activity performed afterward, using the completed warehouse as its data source to discover patterns, trends, and correlations. The actual data warehouse build lifecycle includes requirement gathering (understanding business reporting needs), data modeling (designing star/snowflake schemas, dimensions, and facts), and data profiling (assessing source data quality before ETL) — all of which are genuine construction-phase steps, unlike mining, which is a downstream analytical use case.
