Answer
# 2

Answer: A 

The purpose of the blocking state is to prevent the use of 
looped paths. A port in listening state prepares to 
forward data frames without populating the MAC address 
table. A port in learning state populates the MACaddress 
table but doesn't forward data frames. The forwarding port 
sends and receives all data frames on 
the bridged port. Lastly, A port in the disabled state is 
virtually nonoperational.
