Show answer and explanation

Correct answer: (C) Reconnaissance → field observations → analysis → map

Explanation

Reconnaissance first establishes terrain, access, control and the survey plan. Field observations then provide measurements, which are reduced and analysed before preparing the map. Thus **C** gives the correct dependency order.
