What is third personality liability surrounded by a coup�� insurance?

Hi, I am getting insurance for my car, and it ask me online the amount of third person liability! I don't know what explicitly! Can someone help me, please?
And also what is Collision or Upset (deductible)? is it like what you are liable to pay when you get within an accident?

Answers:

Third person is your passenger. collision pays for your motor if its your fault.
