Select the incorrect variation of gradation of size

1) Cr = Mn = Fe... From Cr to Fe nuclear charge is counter balanced by screeninf effect thus size almost remains constant.2) Ni < Cu < Zn... Due to d10 configuration in Cu,Zn atomic size is abnormally large    Thus from Ni→Cu→Zn→ size increases.3) Se < As < Ge... Left toright in a period atomic size decreases.4) Ti < Zr < Hf... False   Due to lanthaonide contraction size of Zr=Hf  Ti < Zr = Hf
