B. 0.53Å, 1.1 Å, 2.6 Å
C. 2.6Å, 1.1 Å, 0.53 Å
D. 0.53Å, 2.116Å, 2.6 Å

Answer

To solve the question about the radial probability distribution curve for the 2s orbital of the hydrogen atom, we will follow a systematic approach to identify the distances corresponding to the minor maximum, the node, and the major maximum.

### Step-by-Step Solution:

1. **Understand the Radial Probability Distribution**:
- The radial probability distribution curve represents the likelihood of finding an electron at various distances from the nucleus. For the 2s orbital, this curve has two peaks (maxima) and one node.

2. **Identify the Major Maximum**:
- The major maximum for the 2s orbital occurs at a distance of approximately **2.6 Å** from the nucleus. This is where the probability of finding an electron is at its highest.

3. **Identify the Node**:
- The node is a point where the probability of finding an electron is zero. For the 2s orbital, the radial node occurs at a distance of approximately **1.1 Å** from the nucleus.

4. **Identify the Minor Maximum**:
- The minor maximum occurs before the major maximum. For the 2s orbital, this minor maximum is found at a distance of approximately **0.53 Å** from the nucleus.

5. **Summarize the Distances**:
- Therefore, the distances from the nucleus for the minor maximum, the node, and the major maximum are:
- Minor Maximum: **0.53 Å**
- Node: **1.1 Å**
- Major Maximum: **2.6 Å**

### Final Answer:
The distances from the nucleus for the minor maximum, the node, and the major maximum are **0.53 Å, 1.1 Å, and 2.6 Å**, respectively.
