Shahid and Rohit start from the same point in opposite directions. After each 1 km, Shahid always turns left, and Rohit always turns right. Let's analyze their movements:

Assumptions:

• Shahid starts by moving west.
• Rohit starts by moving east.

Shahid's Path:

1. Moves 1 km west.
2. Turns left (south) and moves 1 km.
3. Turns left (east) and moves 1 km.
4. Turns left (north) and moves 1 km.

Rohit's Path:

1. Moves 1 km east.
2. Turns right (south) and moves 1 km.
3. Turns right (west) and moves 1 km.
4. Turns right (north) and moves 1 km.

• After both have traveled 2 km, Shahid is 1 km south of the starting point, and Rohit is 1 km north of the starting point. The distance between them is 2 km.
• They meet after each has traveled 3 km.

Conclusion: The correct statement is:

• B. They meet after each has traveled 3 km.
