Which one is paired incorrectly?

Options

A. Auxin - Isolated from human urine
B. Zeatin - Isolated from corn kernels and coconut milk
C. Gibberellins - Isolated from fungus G. fujikori
D. Abscisic acid - Isolated from ripened oranges

Explanation

To determine which pairing is incorrect, we will analyze each option provided in the question:

1. **Auxin isolated from human urine**: Auxins, specifically Indole Acetic Acid (IAA), were indeed discovered and isolated from human urine by F.W. Wendt. This pairing is correct.

2. **Geatine isolated from corn kernels and coconut milk**: Geatine is a type of cytokinin, and it was discovered by Latham from maize kernels and coconut milk. This pairing is also correct.

3. **Gibberellins isolated from fungus Gibberella fusicularis**: Gibberellins were isolated from the fungus Gibberella fusicularis by Japanese scientists Yabuta, Sumo-ki, and Hiyashi. This pairing is correct as well.

4. **Abscisic acid isolated from ripened oranges**: Abscisic acid was discovered by Addycott and Waring, but it was primarily isolated from mature cotton fruits and not from ripened oranges. The hormone that is typically associated with ripened fruits is ethylene. Therefore, this pairing is incorrect.

### Conclusion:
The incorrect pairing is **abscisic acid isolated from ripened oranges**.

### Steps Summary:
1. Analyze the first option about auxin and confirm it is correct.
2. Analyze the second option about geatine and confirm it is correct.
3. Analyze the third option about gibberellins and confirm it is correct.
4. Analyze the fourth option about abscisic acid and identify it as incorrect.
