Explanation

To solve the question of selecting the pair that contains monocotyledonous families, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Angiosperms**:
- Angiosperms are divided into two main categories: monocotyledons (monocots) and dicotyledons (dicots).
- Monocots have one cotyledon in their seeds, while dicots have two.

2. **Identify Monocot Families**:
- Familiarize yourself with some common monocot families. Examples include:
- Poaceae (Gramineae) - Grass family
- Liliaceae - Lily family
- Orchidaceae - Orchid family
- Arecaceae - Palm family

3. **Evaluate the Given Options**:
- Look at the options provided in the question. Identify which families are monocots.
- For example:
- Solanaceae (Potato family) - Dicot
- Brassicaceae (Mustard family) - Dicot
- Fabaceae (Legume family) - Dicot
- Asteraceae (Daisy family) - Dicot
- Poaceae (Grass family) - Monocot
- Liliaceae (Lily family) - Monocot

4. **Select the Correct Pair**:
- After reviewing the options, select the pair that contains only monocot families.
- In this case, if the options include Poaceae and Liliaceae, then this pair would be the correct answer.

5. **Conclude the Answer**:
- Mark the selected pair as the correct answer to the question.

### Final Answer:
The correct pair that contains monocotyledonous families is **Poaceae and Liliaceae**.
