Marine debris typically
a.
sickens, injures, or kills marine animals
b.
improves water quality
c.
is not a problem for marine organisms
d.
originates from landlocked sources

The answer is 'a. sickens, injures, or kills marine animals'. This is because all other options can be disproven. Option b is false because it's called debris for a reason, option c is false because it definitely poses a problem for marine organisms (have you ever seen a picture of a baby turtle with a soda ring around its neck? Happens all the time.) and d is false because... well, people in landlocked areas usually get their trash in landfills before it has a chance to get into the water system.

Hope this helps and good luck! c:
