To solve the question regarding how eukaryotic, multicellular, saprophytic organisms reproduce sexually, we can follow these steps:
### Step-by-Step Solution:
1. **Identify the Organism Type**:
- The question specifies "eukaryotic, multicellular, saprophytic organisms."
- These characteristics are indicative of fungi, which are known to be eukaryotic and multicellular, and they obtain nutrients by decomposing organic matter (saprophytic).
**Hint**: Remember that saprophytic organisms feed on dead organic matter.
2. **Understand Fungal Reproduction**:
- Fungi can reproduce both sexually and asexually.
- In sexual reproduction, fungi typically produce spores.
**Hint**: Fungi have multiple methods of reproduction; focus on the sexual method for this question.
3. **Identify Types of Spores in Fungi**:
- The main types of spores involved in fungal sexual reproduction include:
- Zygospores
- Ascospores
- Basidiospores
**Hint**: Different types of spores are associated with different groups of fungi.
4. **Evaluate the Options**:
- The question likely provides options related to the types of spores.
- Zygospores, ascospores, and basidiospores are all involved in sexual reproduction in fungi.
- Zoospores and sporangiospores are typically associated with asexual reproduction.
**Hint**: Distinguish between sexual and asexual reproduction when evaluating the options.
5. **Select the Correct Answer**:
- Based on the understanding that zygospores, ascospores, and basidiospores are involved in sexual reproduction, the correct answer would be the option that includes these spores.
- If the question asks which of the given options represents sexual reproduction, the correct choice would be the one that mentions zygospores, ascospores, or basidiospores.
**Hint**: Look for terms that specifically indicate sexual reproduction in fungi.
### Final Answer:
The eukaryotic, multicellular, saprophytic organisms reproduce sexually by forming **zygospores, ascospores, and basidiospores**.
