Answer

To solve the question "In which of the following whole portion of the leaf blade regenerates a new individual?", we can follow these steps:

### Step 1: Understand the Question
The question is asking which plant can regenerate a new individual from the whole portion of its leaf blade. This is a form of vegetative reproduction.

### Step 2: Analyze the Options
We have four options to consider:
- A. Rose
- B. Money Plant
- C. Mango
- D. Kalanchoe

### Step 3: Evaluate Each Option
1. **Rose**: While roses can reproduce through cuttings, they do not regenerate a new individual from the whole leaf blade.
2. **Money Plant**: Similar to roses, money plants can propagate through cuttings, but not from the entire leaf blade.
3. **Mango**: Mango trees reproduce through seeds and grafting, not from leaf blades.
4. **Kalanchoe**: This plant is known for its ability to produce new plants from the edges of its leaves. The leaf blade can regenerate a whole new Kalanchoe plant.

### Step 4: Identify the Correct Answer
Based on the analysis, the only plant that can regenerate a new individual from the whole portion of the leaf blade is **D. Kalanchoe**.

### Final Answer
The correct answer is **D. Kalanchoe**.
