The correct answer is option 2 - the continental shelf along the Western Coast is well pronounced.

The continental shelf refers to the submerged part of the continent that extends from the shoreline to the edge of the continental slope. It is an important fishing ground as it provides a habitat for a variety of marine life.

Option 1, which states that the continental slope along the Western Coast is well developed, is not the correct answer. The continental slope is a steep slope that connects the continental shelf to the ocean depths. While the presence of a well-developed continental slope can contribute to rich fishing grounds, it is not the primary reason for the high level of fishing development along the Western Coast of India.

Option 3, which states that the continental slope along the Western Coast is not well developed, is not correct either. The continental slope along the Western Coast of India is indeed well developed.

Option 4, which states that the continental shelf along the Western Coast is not well developed, is also not correct. As mentioned earlier, the continental shelf along the Western Coast of India is well pronounced, providing a suitable environment for fishing activities.

In summary, the correct answer is option 2 as the well-pronounced continental shelf along the Western Coast of India is a key factor contributing
