Answer:
Correct answer is B. 175 BCE.
Step-by-step explanation:
B is the correct answer because it is the only date that is offered here before the birth of Christ. As this timeline is divided into events that happened before and after the birth of Christ the only correct option is the one that happened before Christ (BCE).
All of other dates that are mentioned in here are after the birth of Christ - 10 CE, 410 CE and 200 CE.
