Among M, N, D, P and K, who earns more than only the least earner among them?
I. N earns more than M and P but less than only D.
II. M earns more than P who earns less than K.

Options

A. the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question,
B. the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question,
C. the data either in statement I alone or in statement II alone are sufficient to answer the question,
D. the data given in both statements I and II together are not sufficient to answer the question,

Explanation

To solve the question, we need to analyze the information given in the two statements and determine who earns more than only the least earner among M, N, D, P, and K.

### Step-by-Step Solution:

1. **Analyze Statement I**:
- N earns more than M and P but less than only D.
- This implies the order: D > N > M, P.
- So, we know that D is the highest earner, followed by N, and then M and P are below N.

2. **Analyze Statement II**:
- M earns more than P, who earns less than K.
- This implies the order: K > P and M > P.
- So, we can place K above P, and since M earns more than P, we can say M > P.

3. **Combine Information**:
- From Statement I, we have D > N > M, P.
- From Statement II, we have K > P and M > P.
- We need to determine the relative positions of M and K.

4. **Possible Orders**:
- Since we know D is the highest, we can consider two scenarios:
- Scenario 1: D > N > K > M > P
- Scenario 2: D > N > M > K > P
- In both scenarios, P is the least earner.

5. **Identify Who Earns More than the Least Earner**:
- The question asks who earns more than only the least earner (P).
- In Scenario 1, K earns more than P.
- In Scenario 2, M earns more than P.
- Therefore, we have two candidates: M and K.

6. **Conclusion**:
- Since we cannot definitively determine the relationship between M and K from the given statements, we cannot conclude who earns more than only the least earner (P).
- Thus, the answer is that it cannot be determined who earns more than only the least earner.

### Final Answer:
The answer is that it cannot be determined who earns more than only the least earner among M, N, D, P, and K. Therefore, the correct option is 4.
