In economics, the law of demand is an economic law, which states that consumers buy more of a good when its price is lower and less when its price is higher (ceteris paribus). The Law of demand states that the quantity demanded and the price of a commodity are inversely related, other things remaining constant. That is, if the income of the consumer, prices of the related goods, and preferences of the consumer remain unchanged, then the change in quantity of good demanded by the consumer will be negatively correlated to the change in the price of the good.

Correct Option: D

Monopolistic competition is a type of imperfect competition such that many producers sell products that are differentiated from one another as goods but not perfect substitutes (such as from branding, quality, or location). In monopolistic competition, a firm takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other firms. In a monopolistically competitive market, firms can behave like monopolies in the short run, including by using market power to generate profit. In the long run, however, other firms enter the market and the benefits of differentiation decrease with competition; the market becomes more like a perfectly competitive one where firms cannot gain economic profit.

The break-even point (BEP) is the point at which cost or expenses and revenue are equal: there is no net loss or gain, and one has “broken even”. A profit or a loss has not been made, although opportunity costs have been “paid”, and capital has received the risk-adjusted, expected return.

Social cost is defined as a sum of the private cost and external costs. The social cost is generally not borne by an individual. It may be borne by entire society, city or even country. This is not a one-time cost like private cost. This cost is recurrent and it is very difficult to calculate due to the inclusion of external costs. The cost may result from an event, action, or policy changes. Social costs are not calculated whenever a seller sells any product or item to buyer. This cost is added up from the use of that product.

Seller’s market is a market which has more buyers than sellers. High prices result from this excess of demand over supply. The opposite of the seller’s market is the buyer’s market, where supply greatly exceeds demand.
