No reaction.
Copper is less reactive than iron and cannot displace Fe2+ from solution. Using standard potentials:
Fe2+ + 2e- → Fe, E° = −0.44 V
Cu2+ + 2e- → Cu, E° = +0.34 V
If Cu were to oxidize and Fe2+ reduce, E°cell = (−0.44) − (+0.34) = −0.78 V (non‑spontaneous), so Cu(s) + FeSO4(aq) gives no reaction.
