$\text { Two isomers of }\left[\mathrm{CoCl}_3\left(\mathrm{NH}_2 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{NHCH}_2 \mathrm{CH}_2 \mathrm{NH}_2\right)\right] \text { are shown below }$


$\text { The correct statement about Isomer-1 and Isomer-2 is }$

• Correct answer
  A

  $\text { Isomer-1 and Isomer-2 are facial and meridional, respectively. }$
• B

  $\text { In Isomer-1 and Isomer-2, all } \mathrm{Cl}-\mathrm{Co}-\mathrm{Cl} \text { and } \mathrm{N}-\mathrm{Co}-\mathrm{N} \text { bond angles are } 90^{\circ} \text {. }$
• C

  Neutral aqueous solution of both these isomers will react with $\mathrm{Ag}^{+}$ion to give AgCl .
• D

  $\text { In Isomer-2, two } \mathrm{Cl}-\mathrm{Co}-\mathrm{Cl} \text { bond angles are } 180^{\circ} \text {. }$

Hence, the correct answer is option: 'A'.
