Answer:
A.
Explanation:
Because as it said in the previous question it said that "a thick dust covered survivors and first responders at ground Zero" If you look at the other questions they do not support the answer u have in the previous question I hope this helps and i am sorry if i a wrong but this is what I think
If you could include more information you could get a more reliable answer, for example what story this is about.
I don’t know I just want my brainly points so I can get an answer to my question, look it up on Symbolab
