Answer

To determine which cross leads to the production of a mule, we need to understand the parent species involved in this hybridization.

### Step-by-Step Solution:

1. **Identify the Parent Species**:
- A mule is a hybrid animal that results from the crossbreeding of a male donkey (jack) and a female horse (mare).

2. **Understand the Crossbreeding Process**:
- Crossbreeding involves mating individuals from two different species or breeds. In this case, we are looking at the mating of a male donkey and a female horse.

3. **Define the Resulting Hybrid**:
- The offspring produced from this specific cross (male donkey x female horse) is known as a mule. Mules are typically sterile, meaning they cannot reproduce.

4. **Evaluate the Options**:
- The question likely provides multiple options for potential crosses. We need to identify which option correctly states the cross that produces a mule.
- The correct option would be: Male donkey (jack) crossed with female horse (mare).

5. **Conclusion**:
- Therefore, the correct answer to the question "Which cross leads to the production of the mule?" is the cross between a male donkey and a female horse.

### Final Answer:
The cross that leads to the production of a mule is **Male Donkey (Jack) x Female Horse (Mare)**.
