8. Monet's later work became increasingly muddy and indistinct, combining longer brush strokes and less color contrast due to his A. loss of physical mobility. B. inability to afford good paint and tools. C. cataracts. D. growing disinterest in painting.

The correct answer is C. Cataracts.

Claude Monet was a French artist who lived between 1840 and 1926. He is considered the father of impressionism and became famous for his art ‘en plein air’. In 1912 he was diagnosed with cataracts, and his bad eye sight led his works to result less clear than his early ones.
