• B. 1,2 and 3
• C. 3,4 and 5
• D. 1, 2 and 4

Answer 1

The correct option is B

1,2 and 3

Tidal energy uses the difference in sea level between high tides and low tides to produce energy. Wave energy uses the kinetic energy of the wave to produce energy. Ocean thermal energy uses the temperature difference between top surface and water at depth to evaporate ammonia, which is further used to run the turbine.
