Explanation:
The question requires determining the fixed number of seats in a football stadium. The information provided states that the stadium has a capacity of 70,000 seats. Therefore, when asked about the fixed number of seats in the stadium, the correct answer is 70,000, making option B the accurate choice. This straightforward question revolves around understanding the term 'fixed number of seats', which in this context, refers to the total number of seats that cannot be changed or exceeded during a football match.
Understanding the context of the query is crucial, as it helps in recognizing that the information about ticket prices and the number sold at different prices, while interesting for economic analysis, does not influence the physical count of seats in the stadium.
