Answer

To solve the problem of matching the species in Column I with their corresponding geometries in Column II, we will follow these steps:

### Step 1: Identify the species and their hybridization
1. **PCl₅**:
- Hybridization: SP³D
- Geometry: Trigonal bipyramidal

2. **ClF₃**:
- Hybridization: SP³D
- Geometry: Bent T shape (due to the presence of lone pairs)

3. **NH₄⁺**:
- Hybridization: SP³
- Geometry: Tetrahedral

4. **H₃O⁺**:
- Hybridization: SP³
- Geometry: Pyramidal (due to one lone pair on oxygen)

### Step 2: Match the species with their geometries
Now, we will match each species from Column I with the corresponding shape from Column II:

- (i) **PCl₅** → (d) **Trigonal bipyramidal**
- (ii) **ClF₃** → (c) **Bent T shape**
- (iii) **NH₄⁺** → (a) **Tetrahedral**
- (iv) **H₃O⁺** → (b) **Pyramidal**

### Final Matching:
- (i) PCl₅ → (d) Trigonal bipyramidal
- (ii) ClF₃ → (c) Bent T shape
- (iii) NH₄⁺ → (a) Tetrahedral
- (iv) H₃O⁺ → (b) Pyramidal

### Summary of the Answer:
- (i) → (d)
- (ii) → (c)
- (iii) → (a)
- (iv) → (b)
