Answer 2

A. Co is the correct answer.

Newlands placed cobalt (Co) and nickel (Ni) in the same group as they have similar properties.

John Newlands put forward his law of octaves in 1864 in which he arranged all the elements known at the time into a table in order of relative atomic mass. When he did this, he found that each element was similar to the element eight places further on.
