Which of the following is not correctly matched?

Options

A. `{:("Name","Stored food"),("Diatoms","Chrysolaminarin and fat"):}`
B. `{:("Name","Stored food"),("Euglenoids","Paramylum and fat"):}`
C. `{:("Name","Stored food"),("Dinoflagellates","Starch"):}`
D. `{:("Name","Stored food"),("Slime moulds","Fucoxanthin"):}`

Answer

To solve the question "Which of the following is not correctly matched?" we need to analyze each option provided regarding the stored food of the given organisms.

### Step-by-Step Solution:

1. **Identify the Organisms and Their Stored Foods:**
- **Option 1: Diatoms - Chrysolaminarin and Fat**
- Diatoms primarily store food in the form of **chrysolaminarin** and **fats**. This option is correctly matched.

- **Option 2: Euglenoids - Paramylon and Fat**
- Euglenoids store food as **paramylon** and some fats. This option is also correctly matched.

- **Option 3: Dinoflagellates - Starch**
- Dinoflagellates primarily store food as **starch**. This option is correctly matched as well.

- **Option 4: Slime Molds - Phycogentin**
- Slime molds store food as **glycogen** and **oil**. The term **phycogentin** is incorrect in this context as it refers to a pigment found in brown algae, not a stored food in slime molds. Thus, this option is not correctly matched.

2. **Conclusion:**
- The incorrect match is found in **Option 4**: Slime Molds - Phycogentin. The correct stored foods for slime molds are glycogen and oil.

### Final Answer:
The option that is not correctly matched is **Option 4**: Slime Molds - Phycogentin.
