Answer»

Correct choice is (b) Reducing scale

To elaborate: Dimensions of large objects MUST be reduced to accommodate on standard drawing SHEETS. It is not any physical instrument but a ratio taken between ACTUAL and drawing objects, the drawing is drawn small and this ratio is TERMED as reducing scale. Don’t get CONFUSED as reducing-scale is also used by surveyors for reducing chains and links to acres and roods.
