Answer» Right answer is (b) A MATERIAL that requires supplementary operations to be USED in manufacturing Easiest explanation: A material that requires supplementary operations before being used in manufacturing is called supplementary operational requirement. The operations vary depending on the material. A few examples are plating, heat treatment ETC. The materials cannot be used in their NATURAL state. This is a disadvantage as it is more costly and time-consuming.
