Why did why did Dorothea Lange decide to photograph farmers during the Great Depression

A. Educate people
B. Record history
C. Change society

Plz help worth 15 points

a. educate people

Explanation:

due to the situation, there was no real way to solve this situation of unemployment/money problems which is why i say the answer is not (c). i would say (a) isnt the answer either because she decided to become a photographer in 1913, before the depression so the reason she was a photographer was not because she wanted to educate people on the depression. (b) seems to be the best choice to me. also she was a documentary photographer and photojournalist so her work is more of a way to inform people. she is not a muckraker either so she wasnt looking to make big reforms in society.
