Answer:
The correct answer is option A.
Step-by-step explanation:
Competitive advantage refers to the situation where a business enjoys superiority over its rivals. The firm is either able to produce at a lower cost or provides more value at the same cost.
The average cost of production for a bottle of vitamin water in the industry is $4 while its average price is $7.
StoreAll Inc. manufactures the same product for $3 per bottle and sells it for $7 per bottle.
Since StoreAll is producing at a lower cost, it will be able to outperform its rivals. This indicates that it has a competitive advantage.
