Show answer and explanation

Correct answer: (A) An underground waterway, tunnelled and channelled; (C) Conducting water from a source-well rather than raising it; (D) Conducting water between enclosures through gravity fall

Explanation

A qanat conveys groundwater through a gently sloping underground channel, using gravity rather than lifting it mechanically. This supports A, C, D. The belt-and-scoop mechanism B is a water-lifting device, not the gravity-fed qanat described by the source.
