B
$d-$orbital are degenerated hence, they form complexes.
✓
Transition metal complexes reflect the complimentary colour of absorbed colour.
D
Energy difference between $\mathrm{t}_{2(\mathrm{g})}$ and $\mathrm{t}_{\mathrm{g}}$ level is very large.

✓

Answer

Correct option: C.

Transition metal complexes reflect the complimentary colour of absorbed colour.

During this $d-d$ transition process, the electrons absorb certain energy from the radiation and emit the remainder of energy as colored light. The color of ion is complementary of the color absorbed by it.
