The Requirement Analysis stage is the initial phase of any AI project cycle.
This stage focuses on understanding what the project aims to achieve and planning how to achieve it.
It involves gathering requirements from stakeholders, defining the scope, and setting clear objectives.
This stage also includes analyzing constraints, risks, and the motivational aspects that drive the project forward.
Design, testing, and deployment come later and depend on clear requirements being defined first.
Without solid requirement analysis, the project can lose direction or fail to meet its goals.
So, the correct answer is option (D) — Requirement Analysis.
