Answer quickly please I really need this answer right now thank you
Which source is an example of a secondary source?
O A. A photograph of someone holding bits of plastic taken from the
ocean
OB. A book about the issue of plastics adding to ocean pollution
O C. A recorded interview with a scientist about the sources of plastics
in the ocean
O D. Data from a study on which oceans are most polluted with
plastics
"A book about the issue of plastics adding to ocean pollution" is the only one that is not from a direct source, the person writing isn't really there so it would be secondary.
