Assertion 
: In the complex 
and 
, the metals have zero oxidation state.
Reason 
: Low oxidation states are found when a complex has ligands capable of 
-donor character in addition to the 
-bonding.
choose the most appropriate answer from the options given below.
A
Both A and R are correct and R is the correct explanation of 
.
