Given below are two statements: one is labelled as "Assertion A" and the other is labelled as "Reason R". Assertion 
: In the complex 
and 
, the metals have zero oxidation state.
Reason R: Low oxidation states are found when a complex has ligands capable of 
-donor character in addition to the 
-bonding.
In the light of the above statements, choose the most appropriate answer from the option given below.
A
is correct but 
is not correct
B
is not correct but

and are correct and is the correct explanation of .
Text Solution
Verified by ExpertsThe correct answer is:
A
