In this question, the correct answer is B. Solid yellow. Here's why:
1. A center line is an indication of a no passing zone to ensure safe driving conditions. When you see a solid yellow line on your side of the center line, it means you are not allowed to pass other vehicles.
2. The other options provided are not correct:
- Broken white lines are used to separate lanes of traffic moving in the same direction.
- Broken yellow lines indicate that passing is allowed when safe to do so.
- None of the above doesn't apply in this case as one of the options is correct.
Remember, it's important to obey road markings like solid yellow lines to promote traffic safety and prevent accidents.
