I am ashamed to say that one bag was missing and two bags were opened illegally . The bag arrived on the next flight from Chicago . The thought of some worker in either Chicago or Indianapolis looking through my personal luggage is unbelievable . But I think it happened in Chicago at the international terminal of American Airlines .
According to the above context, choose the best option to answer the following question.
Question: What about the thought of a worker looking through their bag upsets the speaker so much ?
Options:
- Their bag is full of stolen property , which they are trying to obscure
 - This is their private bag , and no one else has the right to search through it
 - They have contraband in their bag and do n't want anyone to find out
 - None of the above choices .


This is their private bag , and no one else has the right to search through it
