Oceanic tides can be used to generate electricity. Floodgate dams are built across inlets. During high tide water flows into the inlet and gets trapped when the gate is closed. After the tide falls outside the flood gate, the water retained by the floodgate flows back to the sea via a pipe that carries it through a power-generating turbine. In India the Gulf of Khambhat, the Gulf of Kachchh in Gujarat on the western coast and Gangetic delta in Sunderban regions of West Bengal provide ideal conditions for utilising tidal energy.

Correct answer: Option B (ii) - (i) - (iv) - (iii)
Explanation:
The correct sequence of generating tidal energy is as follows:
(ii) Floodgate dams are built across inlets:
Floodgate dams are constructed across inlets to create a controlled area where water can be stored during high tide. These dams help in trapping the incoming tidal water.
(i) During high tide water flows into the inlet and gets trapped when the gate is closed:
When the floodgate is closed, the incoming high tide water gets trapped inside the inlet. This creates a reservoir of water that can be used to generate tidal energy.
(iv) After the tide falls outside the floodgate, the water retained by the floodgate flows back to the sea via a pipe that carries it through a power-generating turbine:
Once the high tide recedes and falls outside the floodgate, the water that is retained inside the inlet is released back to the sea through a pipe. This water flows through a power-generating turbine, which converts the kinetic energy of the flowing water into mechanical energy.
(iii) By this method, oceanic tides can be used to generate electricity:
The mechanical energy generated by the turbine is then used to drive an electric generator, which converts the mechanical energy into electrical energy. This method utilizes the power of oceanic tides to generate electricity.
Therefore, the correct sequence of generating tidal energy is (ii) - (i) - (iv) - (iii).
