Which complex compound is the most stable?

A. $[Co (N H_{3})_{3} (H_{2} O)_{2} Br] (N O_{3})_{2}$
B. $[Co (N H_{3})_{3} (N O_{3})_{3}]$
C. $[CoC l_{2} (en)_{2}] N O_{3}$ ✓
D. $[Co (N H_{3})_{6}]_{2} (S O_{4})_{3}$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
