Only "Put a 3 in front of reactant Fe2" will balance it.

Reason: Xe + 3 Fe2 → XeFe6

Count atoms:
- Xe: 1 = 1
- Fe: 3 × 2 = 6 = 6

Putting a 1 in front of the product does nothing (it's already implicit); putting 6 in front of Fe2 or putting 2 in front of both reactants leaves Fe and/or Xe unbalanced.
