Answer

To solve the question "A pair of monoecious plants are," we need to understand the definitions and characteristics of monoecious and dioecious plants. Here's a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Monoecious Plants**: These are plants that have both male and female reproductive structures (flowers) on the same individual. This means that a single plant can produce both types of flowers.
- **Dioecious Plants**: These are plants that have male and female reproductive structures on separate individuals. Therefore, one plant will produce only male flowers, and another will produce only female flowers.

2. **Identify Examples**:
- Examples of monoecious plants include:
- **Coconut**: It produces both male and female flowers on the same tree.
- **Cucurbita** (e.g., squash, pumpkin): It also has both male and female flowers on the same plant.
- Examples of dioecious plants include:
- **Papaya**: Male and female flowers are found on separate plants.
- **Date Palm**: Similar to papaya, it has separate male and female plants.

3. **Analyze the Options**:
- The question likely provides multiple options, and we need to identify which pair consists of monoecious plants.
- Based on the definitions and examples:
- **Option A**: Contains dioecious plants (e.g., papaya).
- **Option B**: Contains one dioecious and one monoecious plant.
- **Option C**: Also contains one dioecious and one monoecious plant.
- **Option D**: Contains two monoecious plants (e.g., coconut and cucurbita).

4. **Select the Correct Option**:
- After analyzing the options, **Option D** is the correct answer as it contains a pair of monoecious plants.

### Final Answer:
The pair of monoecious plants are found in **Option D** (Coconut and Cucurbita).
