C. Data in either statement 1 alone or in statement 2 alone are sufficient to answer the question.
D. Data in both the statement 1 and 2 not sufficient to answer the question.

Explanation

To determine the marks obtained by Rohit in English in his class-X final exams, we will analyze the information provided in the two statements step by step.

### Step 1: Analyze Statement I
**Statement I:** Rohit scored 42 marks in Chemistry, which was 50% of the marks that he got in Hindi, which is twice as much as the marks obtained in English.

1. **Calculate marks in Hindi:**
- Let the marks obtained in Hindi be \( H \).
- According to the statement, \( 50\% \) of \( H \) is equal to \( 42 \).
- This can be expressed mathematically as:
\[ 0.5H = 42 \]
- Solving for \( H \):
\[ H = \frac{42}{0.5} = 84 \]

2. **Relate Hindi marks to English marks:**
- The statement also mentions that Hindi marks are twice the marks obtained in English.
- Let the marks obtained in English be \( E \).
- Therefore, we have:
\[ H = 2E \]
- Substituting the value of \( H \):
\[ 84 = 2E \]
- Solving for \( E \):
\[ E = \frac{84}{2} = 42 \]

### Conclusion from Statement I:
From Statement I, we find that Rohit scored **42 marks in English**.

### Step 2: Analyze Statement II
**Statement II:** Rohit's marks in English were 17% of the total marks he got in all subjects together.

1. **Let the total marks in all subjects be \( T \).**
- According to the statement, we can express the marks in English as:
\[ E = 0.17T \]
- However, we do not have the value of \( T \) from this statement, so we cannot determine \( E \) directly.

### Conclusion from Statement II:
Statement II alone is not sufficient to determine the marks obtained by Rohit in English, as we do not have the total marks \( T \).

### Final Conclusion:
Since Statement I alone is sufficient to determine the marks obtained by Rohit in English, while Statement II is not, we conclude that the answer is based solely on Statement I.

### Answer:
Rohit scored **42 marks in English**.
