Iron Ore:

1. Iron ores are basically the rock or the minerals from which the metallic iron can be extracted easily.
2. Actually this iron ore can be used for the making of pig iron.
3. Odisha is rich for the iron ores but the presence of Manganese ore is more than that of Iron one.
4. Hence, this option is incorrect.

Option (C):

Magnesium Ore:

1. Magnesium ore is basically known as the Magnesite (${\mathrm{MgCO}}_3$).
2. Actually the Magnesium is obtained by the electrolysis of the Magnesium chloride that was obtained from the oceans
3. Magnesium ore is generally found in the seawater.
4. Hence, this option is incorrect.

Option (D):

Tungsten ore:

1. Tungsten ore is actually known as Wolframite.
2. This is basically a rock from which the element can be extracted economically.
3. Karnataka and Rajasthan are rich in the presence of this ore.
