Option 3 : 1 and 3

The solubility of metallic solids are mainly depends on given below factor (Hume Ruthery rule)

Size factor (difference between the size of host metal atom and impurity atom should be less than 15%).
Valence difference (a metal with lower valence can dissolve large amount of metal of higher valance
Crystal structure
Electro negativity (small between metals)
