1. **Problem Statement:** We are given a figure with angles and lines, and two statements to verify:
- Statement I: The value of $x$ is 130°.
- Statement II: If lines $p \parallel q$, then the value of $a$ is 50°.
2. **Analyzing Statement I:**
- The large triangle has angles 80°, 30°, and 20°.
- The sum of angles in any triangle is always 180°.
- Check if $x = 130°$ fits the triangle angle sum rule.
3. **Triangle Angle Sum Rule:**
$$\text{Sum of angles} = 180°$$
4. **Check the given angles:**
$$80° + 30° + 20° = 130°$$
- This sum is 130°, which is less than 180°.
- Therefore, the angle labeled $x$ cannot be 130° because the triangle's angles must sum to 180°.
- Statement I is **incorrect**.
5. **Analyzing Statement II:**
- Lines $p$ and $q$ are parallel.
- A transversal crosses these lines creating angles 120°, 50°, $a$, and another 50°.
- When two lines are parallel, alternate interior angles are equal.
6. **Using Parallel Lines Property:**
- The angle $a$ corresponds to the alternate interior angle of 50°.
- Therefore, $a = 50°$.
- Statement II is **correct**.
7. **Conclusion:**
- Statement I is incorrect.
- Statement II is correct.
**Final answer:** Option B: Statement-I is incorrect and Statement-II is correct.
