SSC Selection Post 2025 Graduate Level Question Paper (29-Aug-2025) (Shift 1)
The correct answer is

Economies of scale

Economies of scale are the cost advantages a firm gains as it expands output: fixed costs are spread over more units, and bulk buying, specialisation and better technology lower the average (per-unit) cost of production.

The law of diminishing returns says that adding more of a variable input to a fixed input eventually gives smaller increases in output. Opportunity cost is the value of the next best alternative given up. Marginal utility is the extra satisfaction from consuming one more unit.

Hence, the answer is Economies of scale.
