Step 1: Recall what ferromagnetism means.
A ferromagnetic element is strongly attracted by a magnet and can keep a permanent magnetisation, because its atomic magnetic moments line up in the same direction over large domains.
Step 2: Remember the classic examples.
At room temperature the well-known ferromagnetic metals are iron (Fe), cobalt (Co) and nickel (Ni).
Step 3: Check vanadium.
Vanadium is only weakly drawn into a field, so it is paramagnetic, not ferromagnetic.
Step 4: Check chromium.
Chromium has its moments arranged in opposing directions that cancel - it is antiferromagnetic at room temperature.
Step 5: Check manganese.
Manganese also shows antiferromagnetic-type ordering, not ferromagnetism.
Step 6: Choose the match.
Only iron behaves ferromagnetically among the four, so the answer is option (1).
\[ \boxed{\text{Iron is the ferromagnetic element}} \]
