A logistics company has a system that decides whether a shipment needs a customs declaration. The logic was written by a compliance team as a set of conditions taken from published trade rules, and it is updated whenever the rules change. A stakeholder asks whether the company is already using machine learning. What is the accurate answer?

• AYes. Any system that automates a decision a person used to make is machine learning by definition.
• BYes, because the conditions were derived from real trade data held by the compliance team.
• CNo. The behaviour was specified by people rather than learned from data, so it is artificial intelligence without machine learning.
• DNo, and it is not artificial intelligence either, because no model is involved.
