Text Solution
Verified by ExpertsThe correct answer is:
B
CFSE depends on the relative magnitude of crystal field splitting, 
and pairing energy and in turns 
depends upon the field produced by ligand and charge on the metal ion. Here, metal and charge present on it is constant i.e. 
. The order of increasing crystal field strength is 
. Therefore, CFSE follows the order: 
.
