Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The metal carbon bond in metal carbonyls possesses both $$\sigma$$ and $$\pi$$ character.
Reason (R) : The ligand to metal bond is a $$\pi$$ bond and metal to ligand bond is a $$\sigma$$ bond.
In the light of the above statements, choose the most appropriate answer from the options given below.
