To answer this question, you need to understand the correct usage of "fewer" and "less."
Option A) A. lobbied for stadiums with fewer seats to reduce supply and increase ticket prices. - This option is correct because it uses the comparative adjective "fewer" to describe the number of seats in the stadiums. "Fewer" is used when referring to countable nouns, such as seats.
Option B) B. lobbied for stadiums with less seats to reduce supply and increase ticket prices. - This option is incorrect because it uses the comparative adjective "less" instead of "fewer." "Less" is used when referring to uncountable nouns, such as water or money, but not when referring to countable nouns like seats.
Option C) C. lobbied for stadiums that had fewer seats to reduce supply and increase ticket prices. - This option is also correct because it uses the correct form of "fewer" and maintains the meaning of the original sentence.
Option D) D. lobbied for stadiums that had less seats to reduce supply and increase ticket prices. - This option is incorrect because it uses the comparative adjective "less" instead of "fewer."
The correct answer is Option A. This option is correct because it uses the correct comparative adjective "fewer" to describe the number of seats in the stadiums.
