Four statements for the following reaction given below `[CoCl_(2)(NH_(3))_(4)]^(+) to [CoCl_(3)(NH_(3))_(3)]+NH_(3)`
(P) Only one isomer is produced if the ractant complex ion is a trans isomer
(Q) Three isomers are produced if the reactant complex ion is a cis isomer
(R ) Two isomers are produced if the reactant complex ion is trans isomer
(S) Two isomers are produced if the reactant complex is cis isomer
The correct statements are :

Options

A. P and Q
B. R and S
C. P and S
D. Q and R

Answer
