Answer:
ECONOMIES OF SCOPE
Step-by-step explanation:
Economies of Scope concept implies producing different , but related products will reduce the per unit cost of production of the firm (relatively lesser than if the products would have been produced separately.
This happens because of backward & forward linkages in interrelated but different goods' inputs & outputs .
Ex : In this case, another byproduct - molasses has been produced of waste from sugar production, which could have otherwise been purchased input.
Economies of Production is cost reduction due to quantity & not variety production. Diseconomies of Scale & Diseconomies of Scope are their opposite phenomenas leading to cost rise . So , none of these 3 are apt.
