S-I : The quiescent seed germinates on the onset of favourable external conditions.
S-II : Dormancy of seed is due to its internal conditions of the seed

Options

A. S-I and S-II are correct
B. S-I is correct and S-II is incorrect
C. S-I is incorrect and S-II is correct.
D. S-I and S-II are incorrect

Answer

To analyze the statements provided in the question, we will break down each statement and evaluate their correctness step by step.

### Step 1: Analyze Statement S-I
- **Statement S-I**: "The quiescent seed germinates on the onset of favourable external conditions."
- **Explanation**: A quiescent seed is in a dormant state but can germinate when the environmental conditions are suitable (such as adequate moisture, temperature, and light). This statement is correct.

### Step 2: Analyze Statement S-II
- **Statement S-II**: "Dormancy of seed is due to its internal conditions of the seed."
- **Explanation**: Seed dormancy can indeed be attributed to internal factors such as the presence of inhibitors, seed coat characteristics, or developmental maturity. This statement is also correct.

### Step 3: Conclusion
- Both statements S-I and S-II are correct. Therefore, the correct answer is that both statements are true.

### Final Answer
- The correct option is: **Both Statement 1 and Statement 2 are correct.**
