Explanation
Option A - The configuration uses persistent NAT with permit target-host-port;, which allows bidirectional traffic after the initial session has been established by the internal host. Once the NAT mapping is created, the external host can initiate sessions back using the same source/destination IP and port. Option B - The keyword permit target-host-port; restricts the inbound session to the specific external host and port used in the original communication. This is not a general open mapping.
