Final answer:
George Eastman created the Kodak camera and flexible roll film in 1888, making photography more accessible to the general public.
Step-by-step explanation:
In 1888, George Eastman created the Kodak camera and introduced flexible rolls of paper to be used with it. This innovation was a significant advancement in the field of photography as it replaced the then-used photographic plates, making it more convenient for photographers by not requiring them to carry heavy boxes of plates and toxic chemicals. Eastman's Kodak camera came to market with the enticing slogan "You press the button, we do the rest," which became a reality in 1901 with the mass-market introduction of the Kodak Brownie, making photography accessible to even more people. Therefore, the answer to the question is a) George Eastman.
