Which complex possesses a facial $(fac)$ isomer?

Given below are two statements:
Statement-$I$ : The number of paramagnetic species among $[CoF_6]^{3-}$,$[TiF_6]^{3-}$,$V_2O_5$ and $[Fe(CN)_6]^{3-}$ is $3$.
Statement-$II$ : $K_4[Fe(CN)_6] < K_3[Fe(CN)_6] < [Fe(H_2O)_6]SO_4 \cdot H_2O < [Fe(H_2O)_6]Cl_3$ is the correct order in terms of number of unpaired electron$(s)$ in the complexes.
In the light of the above statements,choose the correct answer from the options given below.

In which of the following pairs do both the complexes show optical isomerism?

Identify the correct pair of properties of the $[Co(NH_3)_6]^{3+}$ complex ion.

$A$ complex $[CoL_6]^{n+}$ where $L$ is a neutral ligand has a magnetic moment $\mu = 4.5 \ BM$. Hence,

The number of possible stereoisomers for the complex $[Co(en)_2Cl_2]Cl$ is $(en = \text{ethylenediamine})$.
