EMI stands for electromagnetic interference (which can result in noise and consequently dropped packets), here's a video from the man Professor Messer on the subject:

Also, while 'C' is the only possibly relevant answer, typically an AP (access point) itself wouldn't be DDoS'd. Here's a good article on L4 vs. L7 DDoS:

You are reading too far into the question. Also a DDoS would be towards servers for example.
An AP is installed and immediately packets are dropping. The only answer that makes sense is EMI. -

Indeed EMI is the most likely issue to cause this problem.Bachelor's of Applied Science in Technology Management - Information Security Assurance (St. Petersburg College)
