The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
We are asked who first used the word allelopathy, the term for the harmful or helpful chemical effect one plant has on another nearby plant.
Step 2: Key Formula or Approach:
Allelopathy comes from the Greek words allelon (of each other) and pathos (to suffer), and it describes chemicals released by a plant, through roots, leaves, or residue, that affect the growth of neighboring plants.
Step 3: Detailed Explanation:
The Austrian botanist Hans Molisch coined the term allelopathy in 1937, in his work on chemical interactions between plants.
Holm is better known for his work cataloguing world weeds and compiling weed distribution data, not for naming this concept.
Harper contributed to plant population biology and ecology, including ideas on plant competition, but did not coin this term.
Arnon is known for defining the essential plant nutrients, not for this term.
Step 4: Final Answer:
Molisch is credited with coining the term allelopathy, so option 3 is correct.
