Explanation:

In the complex [Co(NH3)4(NO2)2]Cl, the central cobalt ion is coordinated to four ammonia (NH3) ligands and two nitrite (NO2) ligands. The chloride ion (Cl-) acts as a counterion to balance the charge of the complex.

The different types of isomerism observed in this complex are as follows:

1. Linkage isomerism:
In linkage isomerism, the ligand can coordinate to the central metal ion through different atoms. In this complex, the nitrite ligand (NO2-) can coordinate to the cobalt ion through either the nitrogen atom (N-bound) or the oxygen atom (O-bound). Therefore, the complex can exist in two different forms:

- [Co(NH3)4(NO2)2]Cl (N-bound)
- [Co(NH3)4(ONO)]Cl (O-bound)

2. Ionization isomerism:
In ionization isomerism, the ligands and counterions exchange places. In this complex, the chloride ion (Cl-) and the nitrite ligand (NO2-) can exchange places. Therefore, the complex can exist in two different forms:

- [Co(NH3)4(NO2)2]Cl (nitrite ligand coordinated)
- [Co(NH3)4(NO2)2]NO2 (chloride ion coordinated)

3. Geometrical isomerism:
In geometrical isomerism, the ligands can be arranged in different spatial orientations around the central metal ion. In this complex, the four ammonia ligands (NH3) can be either arranged in a cis configuration or a trans configuration. Therefore, the complex can exist in two different forms:

- cis-[Co(NH3)4(NO2)2]Cl
- trans-[Co(NH3)4(NO2)2]Cl

Conclusion:
From the above explanations, it can be concluded that the complex [Co(NH3)4(NO2)2]Cl exhibits linkage isomerism (N-bound and O-bound), ionization isomerism (nitrite ligand coordinated and chloride ion coordinated), and geometrical isomerism (cis and trans configurations). Therefore, the correct answer is option 'A' - linkage isomerism, ionization isomerism, and geometrical isomerism.
