C. Cladophora ad Cactus
D. Citrus and Euphorbia

Answer

To solve the question regarding the characteristic morphological feature known as 'cladode', we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term 'Cladode':**
- A cladode is a modified stem that resembles a leaf. It is typically flattened and green, allowing it to perform photosynthesis.

2. **Identify the Characteristics of Cladodes:**
- Cladodes are usually found in plants where the leaves are reduced or absent. They serve the purpose of photosynthesis and can store water.

3. **Review the Options Provided:**
- The options given are:
- A) Asparagus and Druscus
- B) Casuarina and Opuntia
- C) Cladophora and Cactus
- D) Citrus and Euphorbia

4. **Analyze Each Option:**
- **Option A (Asparagus and Druscus):** Asparagus has cladodes, which are modified stems. Druscus is not a commonly known plant but could refer to Dracaena, which also has similar features.
- **Option B (Casuarina and Opuntia):** Both are known for having phylloclades (modified stems), but they do not specifically refer to cladodes.
- **Option C (Cladophora and Cactus):** Cladophora is an algae and does not have cladodes. Cactus has spines instead of leaves.
- **Option D (Citrus and Euphorbia):** Citrus has thorns, and Euphorbia has fleshy stems, neither of which are cladodes.

5. **Determine the Correct Answer:**
- The only option that correctly identifies a plant with cladodes is **Option A (Asparagus and Druscus)**.

### Final Answer:
The correct answer is **Asparagus and Druscus**.
