Regarding continental shelf, consider the following statements: 1. In...
- The width of the continental shelf varies considerably - it is not uncommon for an area to have virtually no shelf at all, particularly where the forward edge of an advancing oceanic plate dives beneath continental crust in an offshore subduction zone such as off the coast of Chile or the west coast of Sumatra where they are mountainous.
- The largest shelf - the Siberian Shelf in the Arctic Ocean - stretches to 1,500 km in width. Continental shelves are the richest fishing grounds.

Regarding continental shelf, consider the following statements: 1. In...
Explanation:
The correct answer is option 'C' i.e., 1 and 3 only. Let's understand why the other statements are correct and why these two statements are incorrect.
Statement 1: In mountainous coasts, continental shelves are broad.
This statement is correct. The width of the continental shelf varies depending on the topography of the coastline. In mountainous coasts, the continental shelves tend to be broader because the mountains extend underwater, resulting in a wider shelf.
Statement 2: The continental shelf is an underwater landmass which extends from a continent.
This statement is correct. The continental shelf is the shallow submerged extension of a continent. It is part of the continental crust and is located between the shoreline and the continental slope. It gradually slopes down from the shoreline to the deeper ocean floor.
Statement 3: The continental shelves are poor in fish resources as they are shallow.
This statement is incorrect. Continental shelves are actually rich in fish resources. They provide a productive and diverse ecosystem for fish and other marine organisms. The shallow waters of the continental shelves are ideal for the growth of phytoplankton, which forms the base of the marine food chain. This abundance of phytoplankton attracts small fish and other organisms, which in turn attract larger fish. Therefore, continental shelves are often important fishing grounds and support commercial fisheries.
Conclusion:
Based on the above explanation, it can be concluded that statements 1 and 3 are incorrect. The correct answer is option 'C' i.e., 1 and 3 only.
