Nathan is creating a document that needs to be accessible to people with visual impairment.He should do what to the pictures in the document?

A) Reset the pictures.
B) Add appropriate alt text to each of the pictures.
C) Add an artistic effect to each of the pictures.
D) Set the text wrapping to In Front of Text.

Adding appropriate alt text to each of the pictures would make them accessible to people with visual impairment. Alt text provides a textual description of the image and is read aloud by screen readers for those who can't see the image. Resetting the pictures, adding an artistic effect, or setting the text wrapping to In Front of Text does not provide an accessibility benefit to visually impaired users.
