Correct option is D
Tidal energy is generated through the movement of water caused by the rise and fall of tides, driven primarily by the gravitational pull of the moon and sun. Coastal regions with a large tidal range (difference between high and low tides) are ideal for harnessing tidal energy. The Gulf of Kutch, located on the western coast of India, is known for having a high tidal range, making it one of the main areas in India suitable for tidal energy production. In contrast, the Gulf of Mannar and the Gulf of Khambhat, though significant water bodies, do not exhibit as large a tidal variation. The Gulf of Bengal is a vague geographical reference and is not a term used in energy contexts. Notably, India has explored tidal energy potential at various locations, including the Gulf of Kutch. However, it remains underdeveloped compared to other renewable sources like solar and wind energy. Future developments in this area could play a crucial role in India's renewable energy portfolio.
