The correct answer is - C. Providing adequate drainage.
By providing an adequate water drainage the chances of experiencing a water hazard are significantly reduced and mostly preventable. An adequate water drainage will enable two things:
- the water will have a free flow in a way organized by the people, so that it can go away from the critical points, and get easy and without any barriers to a bigger water body;
- the accumulation of water on certain places will be avoided as the water will be able t move easily and freely. The accumulation of large amounts of water on certain places can lead to big floods and destruction, and with the drainage system that will be avoided;
