Answer:
The correct answer is D. choosing to move in order to work at a better job
Step-by-step explanation:
D is the correct option because it is the only one where someone has an option of moving. The person obviously has a job, but WANTS to move because he has a better option.
Option A is wrong. He or she is forced to move, meaning that someone made him/her.
B is also wrong because nature forced him to move. There is no other option.
C is also wrong. He/she has nothing to choose from. Moving is the only option.
