    Iron
  2. B
    Chromium
  3. C
    Zinc
  4. D
    Manganese

Solution & Step-by-step Explanation

Let's look at the atomic numbers (Z) of the given elements in the 3d transition series of the periodic table:
Copper (Cu): Z=29

Iron (Fe): Z=26

Chromium (Cr): Z=24

Zinc (Zn): Z=30

Manganese (Mane): Z=25

Since 30>29, Zinc has an atomic number greater than that of Copper.
