Answer:
The correct answer is A. Jacob Riis is famous because he took photographs of immigrants and the problems they faced.
Explanation:
Jacob August Riis was a Danish-American photographer, one of the founders of documentary photography. He is known as a fighter against social inequality, who tried to reflect in his works the life of the “lower classes” of New York. Riis also belongs to the pioneers of photography, as he was the first photojournalist to start using the flash.
Riis joined the New York Tribune, where he worked as a police reporter, where his work enabled him to go with the police in raids in slums on the lower east side of Manhattan where gangsters, brothels and gambling halls were raided. There he was shocked by what he saw from the misery, poverty and ignorance and realized the extent of the gross injustice suffered by those crushed groups, which society did not know or care about.
