C. ii and iii
D. Only iv

Answer

To solve the question "Which of the following is not related with kingdom Protista?" we need to analyze each of the statements provided:

1. **Chief producers in ocean are diatoms.**
- Diatoms are indeed a type of phytoplankton and are considered one of the chief producers in marine ecosystems. They play a crucial role in the food chain and contribute significantly to primary production in oceans. This statement is **true**.

2. **Some members show bioluminescence.**
- Certain members of the kingdom Protista, such as dinoflagellates (e.g., Noctiluca scintillans), are known to exhibit bioluminescence. This phenomenon is common in marine environments and is due to biochemical reactions within these organisms. This statement is also **true**.

3. **These include golden algae.**
- Golden algae, or chrysophytes, are indeed part of the kingdom Protista. They are characterized by their golden-brown pigments and are a significant group of algae. This statement is **true**.

4. **Many members are multicellular.**
- This statement is **not true** for kingdom Protista as a whole. While there are some multicellular forms (like certain algae), the majority of protists are unicellular. Therefore, this statement does not accurately represent the kingdom Protista.

Based on the analysis above, the statement that is **not related** to kingdom Protista is:

**Answer: (iv) many members are multicellular.**
