If drone images show regular differences in crop colour, what may be a possible interpretation?
Answer and explanation
Correct answer: Buried structures may be affecting plant growth
The governing concept is crop-mark interpretation in aerial or drone survey. Buried walls, floors, ditches, and pits can alter soil depth, drainage, or moisture, causing plants above them to differ in colour or density from nearby growth. A regular ground-related pattern may therefore indicate buried remains, although it still requires verification. Option A is correct; the other choices do not explain a patterned archaeological signal adequately.
