Step 1: [Fe(ox)3]3-.
Octahedral tris-bidentate: propeller geometry, no plane/centre of symmetry → chiral. Statement I = correct.
Step 2: trans-[Cr(H2O)2(ox)2]-.
Trans arrangement: plane of symmetry exists → achiral. Statement II = incorrect.
Step 3: Final.
\[ \boxed{\text{Statement I correct, Statement II incorrect}} \]
