Claire B

Out of the two options, the Claire B scenario is non-canon.

Story
Claire Redfield rides into Raccoon City on her motorbike looking for her brother Chris. When she searches a restaurant, she is approached by a Zombie. Heading for the back door, she is introduced to another survivor; Leon S. Kennedy.

The police cruiser they commandeer crashes backwards into a lamp post and the two get out of the car just in time to escape the impact of a fuel truck with the cruiser.

Whilst on her way to the Police Department, Claire bears witness to a Helicopter crash, as a Police officers sub-machine gun hits the pilot.

Claire encounters Leon again in the S.T.A.R.S. Office. The two collect radios to communicate and leave.

Claire encounters a fourth and fifth survivor; Sherry Birkin and Brian Irons. Claire and Sherry later follow Irons' route down a secret room in his office. There, Claire witnesses monster pull Irons down a trap door, where his upper torso is thrown back up.
