Explanation:

Manganese Nodules is a type of sediment scattered on the ocean floor, consisting mainly of manganese and iron, and usually containing small amounts of copper, nickel and cobalt.
Statement 1: Presently, there is no production of cobalt in the country from indigenous ores. The refined production of cobalt is from imported feed material.
Cobalt is used in medical treatment and nickel in batteries. Thus,mining for these is of strategic importance as there is no terrestrial source of these metals in India.
The nodules on the Indian Ocean bed are found at a depth of about six thousand metres and the closest point of the nodule fields is at a distance of about two thousand five hundred km off the Kanyakumari coast.
