Answer:
The correct option is;
They can be produced at low cost
Explanation:
In comparison to several other manufacturing materials, some synthetic polymers such as plastics are more durable cost effective, flexible, faster to produce and reliable
With regards to the cost comparison, the resins used for plastic are cheaper to obtain than mining for materials such as metals. In all quantities, it is cheaper to produce and manufacture plastics than to produce metals.
Due to the light weight and corrosion resistance of plastics, it is cheaper to store and transport plastics to several locations with different environment without the plastic requiring much effort for transportation or being affected by corrosion.
