  • A. Linen or cloth tape

Correct Answer: Option B - Metallic tape– It is a linen tape with brass or copper wires woven into it longitudinally to reduce streching. As it is varnished the wires are not visible. These are available in length of 20-30 m. It is an accurate measurement device and is commonly used for measuring offsets. As it is reinforced with wires, all the defects of linen tapes are overcome.
