Answer

To solve the question regarding the correct combinations of flowering plant families and their respective arrangements of stamens, we will analyze each family one by one.

### Step-by-Step Solution:

1. **Brassicaceae Family**:
- The Brassicaceae family has 6 stamens arranged in 2 whorls.
- The arrangement is specifically 4 long stamens and 2 short stamens (2 + 4).
- Therefore, the correct representation for Brassicaceae is **A(2+4)**.
- **Match**: (a) Brassicaceae → **iv A(2+4)**.

2. **Fabaceae Family**:
- The Fabaceae family has 10 stamens, which are diadelphous (united in two groups).
- The arrangement is 9 stamens in one group and 1 stamen in another (9 + 1).
- Therefore, the correct representation for Fabaceae is **A(9+1)**.
- **Match**: (b) Fabaceae → **ii A(5)**.

3. **Solanaceae Family**:
- The Solanaceae family has 5 stamens arranged as epipetalous.
- The representation for Solanaceae is **A(5)**.
- **Match**: (c) Solanaceae → **ii A(5)**.

4. **Liliaceae Family**:
- The Liliaceae family has 6 stamens arranged in 2 whorls, with each whorl containing 3 stamens (3 + 3).
- Therefore, the correct representation for Liliaceae is **A(3+3)**.
- **Match**: (d) Liliaceae → **i A(3+3)**.

### Summary of Matches:
- (a) Brassicaceae → **iv A(2+4)**
- (b) Fabaceae → **ii A(5)**
- (c) Solanaceae → **ii A(5)**
- (d) Liliaceae → **i A(3+3)**

### Final Answer:
The correct combinations are:
- A is 4
- B is 3
- C is 2
- D is 1

Thus, the final answer is **option number 3**.
