Answer:
1. Litter is not only ugly, but also harmful to animals in national parks
Step-by-step explanation:
When writing an essay in support of a point, you have to select salient points that are consistent and relatable to what you're writing about..
Younique is writing an essay in support of recycling to reduce garbage in the ocean and therefore she has to bring points that relates to side effects of throwing garbage in the ocean, how easy it is to recycle garbage and other necessary points.
The truly odd one out is option A which says "Litter is not only ugly, but also harmful to animals in national parks".
This has no direct connection to effect of garbage in the ocean or recycling so this is the piece of evidence with the least relevance to her argument.
