To solve the question "Choose the odd one with respect to sexuality," we will analyze the options provided: coconut, cucurbit, cara, and papaya.

### Step-by-Step Solution:

1. **Understand the Terms:**
- **Monoecious:** A plant that has both male and female reproductive organs on the same individual.
- **Dioecious:** A plant that has male and female reproductive organs on separate individuals.

2. **Identify the Options:**
- **Coconut:** This plant has both male and female flowers on the same plant, making it monoecious.
- **Cucurbit:** This group of plants (like cucumbers and pumpkins) also has both male and female flowers on the same plant, so it is monoecious.
- **Cara:** Similar to coconut and cucurbit, cara (also known as taro) is monoecious as it has both male and female reproductive structures on the same plant.
- **Papaya:** This plant is dioecious, meaning it has separate male and female plants.

3. **Determine the Odd One Out:**
- Since coconut, cucurbit, and cara are all monoecious, while papaya is dioecious, papaya is the odd one out.

4. **Conclusion:**
- The odd one with respect to sexuality is **papaya** (option 4).
