D. Cobalt has one less proton.

Explanation:

Comparing a typical nickel and cobalt atom suggests that cobalt has one less proton in its nuclear space.

Cobalt has an atomic number of 27

Nickel has an atomic number of 28

Cobalt and nickel are both transition metals found in the d-block on the periodic table.

Atomic number is the number of protons in the nucleus of an atom.

We can see that Nickel has 1 more proton compared to cobalt.
