Explanation

To solve the problem of matching the complexes in Column I with the types of isomerism in Column II, we will analyze each complex and determine the correct type of isomerism based on the characteristics provided.

### Step-by-Step Solution:

1. **Identify the Complexes and Their Components:**
- **(A)** CoCl₃·5NH₃·H₂O
- **(B)** Co(NH₃)₅BrSO₄
- **(C)** CrCl₃·6H₂O
- **(D)** Cr(NO₂)₂·6H₂O

2. **Analyze Each Complex:**
- **For (A) CoCl₃·5NH₃·H₂O:**
- This complex can show **hydrate isomerism** because it can exchange water molecules.
- It also satisfies its secondary valency with neutral ligands (NH₃ and H₂O).
- Therefore, it matches with (s) "Show hydrate isomerism".

- **For (B) Co(NH₃)₅BrSO₄:**
- This complex can show **ionization isomerism**. When dissolved in water, it can produce different ions (Br⁻ and SO₄²⁻).
- The magnetic moment can also be calculated, and it is likely to be around 3.87 B.M. due to the presence of unpaired electrons.
- Thus, it matches with (q) "The magnetic moment of one of the isomers form is 3.87 B.M.".

- **For (C) CrCl₃·6H₂O:**
- This complex can show **ionization isomerism** as well, where the exchange of Cl⁻ and H₂O can occur.
- It can also show **hydrate isomerism** due to the presence of water.
- However, since it is primarily characterized by the exchange of ions, it matches with (r) "Show ionization isomerism".

- **For (D) Cr(NO₂)₂·6H₂O:**
- This complex can show **linkage isomerism** because the NO₂ ligand can coordinate through either nitrogen or oxygen.
- It also shows **hydrate isomerism** due to the presence of water.
- Therefore, it matches with (t) "Show linkage isomerism".

3. **Final Matching:**
- (A) CoCl₃·5NH₃·H₂O → (s) "Show hydrate isomerism"
- (B) Co(NH₃)₅BrSO₄ → (q) "The magnetic moment of one of the isomers form is 3.87 B.M."
- (C) CrCl₃·6H₂O → (r) "Show ionization isomerism"
- (D) Cr(NO₂)₂·6H₂O → (t) "Show linkage isomerism"

### Summary of Matches:
- **A → s**
- **B → q**
- **C → r**
- **D → t**
