MHT CET Chemistry question

The ion is reducing agent while that of is an oxidising agent though both have configuration. This is because

(A) configuration results from to while that of results from highly stable configuration.
(B) configuration results from to while that of results from highly stable configuration.Correct
(C)Both the ions, and results from configuration.
(D) configuration results from while that of Mn results from .

Answer: (B)

Cr () is oxidised to Cr (, stable half-filled t configuration) and so is a reducing agent, while Mn () is reduced to
