Answer

To solve the question "Male and female flowers are present on the same plant in all of these, except:", we will analyze each option provided and determine whether the plants are monoecious (having both male and female flowers on the same plant) or dioecious (having male and female flowers on separate plants).

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Monoecious**: Plants that have both male and female flowers on the same individual. Examples include corn (maize), fig, and coconut.
- **Dioecious**: Plants that have male and female flowers on separate individuals. An example is the date palm.

2. **Analyzing the Options**:
- **Option A: Fig**: Fig trees are monoecious as they have both male and female flowers on the same tree.
- **Option B: Coconut**: Coconut palms are also monoecious, having both male and female flowers on the same plant.
- **Option C: Maize**: Maize is another example of a monoecious plant, with both types of flowers present on the same plant.
- **Option D: Date Palm**: Date palms are dioecious; male and female flowers are found on separate plants.

3. **Conclusion**:
- Since the question asks for the plant where male and female flowers are not present on the same plant, the correct answer is **Option D: Date Palm**.

### Final Answer:
**D: Date Palm**
