B Correct answer
Explanation

Using the Principle of Inclusion-Exclusion, the number of people watching at least one movie is 13000 + 10500 - 2500 = 21000. The number of people watching neither is 25000 - 21000 = 4000. The percentage is (4000/25000) * 100 = 16%.

AI explanation

Using the principle of inclusion-exclusion for two sets, the number of people who watch at least one type of movie is 13000 + 10500 - 2500 = 21000. The population that watches neither movie is the total population minus this value, giving 25000 - 21000 = 4000. The required percentage is (4000 / 25000) multiplied by 100, which equals 16%.
