A) Molecular chains shift from a random orientation to align parallel to each other in the direction of the pulling force
B) During the pulling,the mixed-up polymer chains cross link to make the polymer stronger
C) The pulling force creates branches,causing a switch from high density to low density polymer
D) It is only a temporary distortion;once the pulling force stops,the plastic snaps back to the original orientation
