Market structure is defined with characteristics of the market and there are four different market structures: perfect competition, oligopoly, monopoly and contestable market.
<span>Perfect competition is a market structure in which there is a large number of small firms who produce identical goods otherwise known as homogenous goods and it has a lot of buyers. The competition between these firms is huge, because they are many firms and each of them wants to attract more buyers.</span>
Oligopoly is a market structure in which there is a small amount of large firms, for example the supermarket industry.

Answer: c. Contribution margin ratio = 1 − Variable cost ratio
Explanation:
The Contribution margin ratio is defined as the difference between the sales price of a good and it's variable costs. It is expressed as a percentage.
The formula is,
Contribution Margin Ratio = Sales - Variable Costs / Sales
Breaking the formula down further we have,
Contribution Margin Ratio = Sales/ Sales - Variable Costs / Sales
Contribution Margin Ratio = 1 - Variable Costs / Sales
Variable Cost/Sales is the Variable Cost Ratio.
So Option C is correct.
