Answer

To solve the question "Find the correct match," we will analyze each option provided and determine which matches correctly with the diseases caused by the respective fungi.

### Step-by-Step Solution:

1. **Analyze the first option: Phytophthora infestans**
- This organism is known to cause late blight of potato, not early blight.
- Therefore, this option is incorrect.

2. **Analyze the second option: Albugo candida**
- Albugo candida is indeed known to cause white rust of crucifers.
- This option is correct.

3. **Analyze the third option: Paxina gravenis**
- Paxina gravenis is associated with wheat rust.
- This option is also correct.

4. **Analyze the last option: All of the above**
- Since the first option is incorrect, "all of the above" cannot be a correct answer.
- Therefore, this option is also incorrect.

### Conclusion:
The correct matches are:
- Albugo candida causes white rust of crucifers.
- Paxina gravenis causes wheat rust.

Since only Albugo candida and Paxina gravenis are correct, the answer is not "all of the above."

### Final Answer:
The correct match is Albugo candida for white rust of crucifers.
