| Column- I | Column- II |
|---|---|
| A) Auxin | I) Yabuta and Sumiki |
| B) Gibberellin | II) Denny, Gane and Crocker |
| C) Cytokinin | III) Kogl and Smit |
| D) Ethylene | IV) Skoog and Miller |
Options
- AA - III, B - I, C - IV, D - II
- BA - I, B - III, C - II, D - IV
- CA - IV, B - II, C - I, D - III
- DA - IV, B - III, C - II, D - I
Correct answer
A. A - III, B - I, C - IV, D - II
Step-by-step solution
Auxin was isolated by Kogl and Haagen-Smit from human urine.
Gibberellin was isolated in crystalline form by Yabuta and Sumiki from the fungus Gibberella fujikuroi.
Cytokinin (kinetin) was isolated and identified by Skoog and Miller from herring sperm DNA.
Ethylene was identified as a gaseous plant hormone by Denny, Gane, and Crocker.
Therefore, the correct matching is A - III, B - I, C - IV, D - II.
Answer: A - III, B - I, C - IV, D - II
