Answer 2

The surveying method of choice would be hydrographic surveying. (Option C)

• While building a bridge over a water body it is essential to know the depth of the bedrock, its nature, and structural composition as these are the factors that can affect the foundation of the bridge.
• Hydrographic surveying will help to study all these geological characteristics.
