The correct answer is B) The accused person will attend the trial.
Payment of bail is supposed to guarantee "The accused person will attend the trial."
This happens when someone who is arrested pays cash or property to the court to assure that he/she will appear on court when needed. This way, people can leave jail and wait to be called to court. If for any reason the individual does not show up, the court can issue a warrant to arrest the individual and also the court can keep the bail. So you better do the right thing and never set foot in jail.
