  Both are incorrect.

• D. Only II is correct.
  
  

Answer 1

The correct option is C Only I is correct.


An element is a substance that is made entirely from one type of atom. This means that an element of Iron will only be composed of Iron particles. Similarly, the element Nickel will be made only of Nickel. On the other hand, a Nickel ore can have a combination of elements in it. A Nickel ore has a high amount of Nickel but also some amount of Iron and other elements.
