Question Analysis:
This question tests the ability to combine rotations of opposite directions (CW and CCW) by converting them to a common standard (CCW).

Key Concept Explanation:
Clockwise (CW) to Counterclockwise (CCW) Conversion: CCW = 360° − CW.
Net Rotation: Sum individual rotations in CCW terms, then simplify modulo 360°.

Step-by-Step Solution:
Convert 150° CW to CCW: 360° − 150° = 210° CCW.
Second rotation is already 210° CCW.
Add rotations: 210° CCW + 210° CCW = 420° CCW.
Simplify modulo 360°: 420° − 360° = 60° CCW.

Option Analysis:
A) Incorrect: Misinterprets net direction as CW.
B) Correct: Proper conversion and simplification.
C) Incorrect: Only true if rotations cancel perfectly ...
