Amalia has the flu, a communicable disease that causes a cough and a runny nose. which best describes how she likely got it?

Based on the scenario, the best one that describes how she likely got it is : she touched the doorknob in her classroom

one of her friends in the classroom probably a carrier or an infected of the virus. when that friends touch the doorknob, the viruses resided in that place and transmitted to amalia when she touched the door knob

hope this helps

Yes yes yes very good
