Pulsation theory was proposed by

Options

A. Godlewski
B. J.C. Bose
C. Dixon and Joly
D. Arthur

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks who proposed the pulsation theory.

2. **Review the Options**: The options provided are Goldlewisky, J.C. Bose, Dixon, Jolly, and Arthur.

3. **Recall Relevant Information**: The pulsation theory is associated with the absorption of water by plants. It suggests that water is absorbed due to the metabolic activities of living cells that are in a constant state of rhythmic pulsation.

4. **Identify the Proposer**: According to the information, Sir J.C. Bose is credited with proposing the pulsation theory.

5. **Consider Acceptance of the Theory**: Although J.C. Bose proposed this theory, it was not widely accepted because it was later observed that water can be absorbed by roots even when the cells are dead, indicating that there are passive mechanisms for water absorption.

6. **Conclude the Answer**: Therefore, the correct answer to the question is J.C. Bose.

**Final Answer**: The pulsation theory was proposed by J.C. Bose.
