Explanation

To solve the question of matching compounds from List I with their respective molecular geometries in List II, we will analyze each compound one by one.

### Step-by-Step Solution:

1. **Identify the structure of CS₂ (Carbon Disulfide)**:
- CS₂ has a linear structure because the carbon atom is bonded to two sulfur atoms with double bonds.
- **Match**: CS₂ → Linear (Q)

2. **Identify the structure of SO₂ (Sulfur Dioxide)**:
- SO₂ has a bent structure due to the presence of a lone pair of electrons on the sulfur atom, which pushes the oxygen atoms closer together.
- **Match**: SO₂ → Bent (P)

3. **Identify the structure of BF₃ (Boron Trifluoride)**:
- BF₃ has a trigonal planar structure because the boron atom is bonded to three fluorine atoms with no lone pairs, allowing for a symmetrical arrangement.
- **Match**: BF₃ → Trigonal planar (R)

4. **Identify the structure of NH₃ (Ammonia)**:
- NH₃ has a trigonal pyramidal structure because the nitrogen atom is bonded to three hydrogen atoms and has one lone pair of electrons, which alters the geometry from a perfect tetrahedral to trigonal pyramidal.
- **Match**: NH₃ → Trigonal pyramidal (T)

### Summary of Matches:
- (a) CS₂ → (q) Linear
- (b) SO₂ → (p) Bent
- (c) BF₃ → (r) Trigonal planar
- (d) NH₃ → (t) Trigonal pyramidal

### Final Answer Codes:
- A → Q
- B → P
- C → R
- D → T

The correct answer option based on the matches is **A → Q, B → P, C → R, D → T**.
