C. "Granting amnesty encourages the violation of our laws, and perpetuates illegal immigration."
I'd go with A or C. Definitely not B or D.
I think it’s to fasten firmly. After the word secure it says “or attach”.
Simile, because a simile needs like or as in the sentence
Well it isn’t C. Or D.
For a lil bit I was tied between A. And B.
But I figured out it is A.
Hope that I could help you
