Given below are two statements:
Statement $I$: Iron$(III)$ catalyst,acidified $K_{2}Cr_{2}O_{7}$ and neutral $KMnO_{4}$ have the ability to oxidise $I^{-}$ to $I_{2}$ independently.
Statement $II$: Manganate ion is paramagnetic in nature and involves $p\pi-p\pi$ bonding.
In the light of the above statements,choose the correct answer from the options.
