The correct answer is B. The centerline depicted in a drawing or blueprint is typically represented by a solid, thin line with long dashes, as shown in option B. This is the standard convention for representing the centerline in technical drawings and blueprints. The other options do not accurately depict the centerline symbol. Option A shows a solid, continuous line, which is not the correct representation for a centerline. Options C and D show different line styles that are not typically used to denote the centerline in engineering drawings.
