Answer:
The correct answer is - aerial view of the fault line of San Andreas which represents a transform or strike-slip type of boundary.

The picture is given in the question is an aerial view of the fault line of San Andreas.
A fault is a planar break or intermittence in a volume of rock across due to rock-mass movement that leads to significant relocation or displacement. In San Andreas, the faultline represents the transform or strike-slip type of boundary.
Observation:
- A complex zone of crushed and broken rock
- Many smaller faults branch
