Final answer:
The most accurate statement regarding a business's success in relation to costs is that cost determines the success of pricing decisions and execution. However, it must be compared along with other factors such as sales, revenue, and market structure.
Step-by-step explanation:
When considering which statement is correct regarding the success of a business, it's important to take into account various factors related to the cost structure and market conditions. Statement (a) suggests a company must cover all costs to remain successful, which is generally true, as profitability requires revenue to exceed costs. However, it's more complex than just covering costs. Statement (b) talks about attracting customers through a cost advantage, which can be a strategy for some businesses but does not universally ensure success. Statement (c) is incorrect as cost is not the only indicator of price sustainability; other factors like value perception, demand, and competition also play critical roles. Statement (d) is the most accurate. Cost determines the success of pricing decisions and execution, though it is not the sole determiner, as it must be considered along with sales, revenue, market structure, and other factors.
