Answer

To determine which statement is not related to the kingdom Protista, we will analyze each option one by one.

1. **Chief producers in the ocean are diatoms.**
- Diatoms are indeed a major group of algae and are considered primary producers in marine ecosystems. They perform photosynthesis and contribute significantly to the ocean's food web. Therefore, this statement is **true** and related to kingdom Protista.

2. **Some members show bioluminescence.**
- Certain protists, particularly dinoflagellates, are known for their ability to produce light through bioluminescence. This phenomenon is observed in some marine environments. Hence, this statement is also **true** and related to kingdom Protista.

3. **These include golden algae.**
- Golden algae, or chrysophytes, are a group of protists that are indeed classified within the kingdom Protista. This statement is **true** and related to kingdom Protista.

4. **Many members are multicellular.**
- This statement is **not true** for kingdom Protista. Most protists are unicellular, and while there are some multicellular forms (like certain algae), they are not as common as unicellular forms. Therefore, this statement does not accurately represent the characteristics of kingdom Protista.

Based on the analysis, the statement that is **not related** to kingdom Protista is option **4**: "Many members are multicellular."

**Final Answer:** Option 4
