B. natural movement of tides

Explanation:

Tidal energy is a form of electricity generation from tidal changes and natural tidal movement through dams (which take advantage of the height difference between high and low tides) or through submerged turbines ( that take advantage of the sea currents). The most used system is that of dams, which consists of the construction of pipeline that capture the water during the high tide. This stored water is then released during low tide through a turbine that generates electricity.

A tidal power plant requires three basic elements: powerhouse or power generating units, locks, to allow water into and out of the basin, and dams.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
