In order to indicate that a cylindrical solid shape has been shortened, cylindrical break lines are used. These break lines indicate that the shape remains constant throughout the entire length, but a portion has been removed for clarity in the drawing. A short, thick, slightly irregular break line (as described in choice B) or a jagged, thick, very irregular break line (as described in choice C) would not accurately represent the shape of the cylinder. Therefore, only choice A is true.
