Ti3+
Stability to transition metal ion is directly proportional to the unpaired electron. The exactly half filled and completely filled d - orbitals are extra stable.
Cr3+ (21) = 3d3 4s0 -3 unpaired electrons
V3+ (20) = 3d2 4so -2 unpaired electrons
Ti3+ (19) = 3d1 4s0 -1 unpaired electron
Mn3+ (22) = 3d4 4so - 4 unpaired electrons
So, Mn3+ ion is most stable in aqueous solution.
