Explanation
Configuring a BGP peer requires only the neighbor's IP address and AS number at a minimum - without these two, the BGP session cannot be established, making B and D incorrect choices (they ARE required). A password (MD5 authentication) is entirely optional; it adds security but BGP peers will form a session without it, so A is not required. A description is purely an administrative label for human readability and has no effect on the BGP session itself, making C also not required.
Memory tip: Think of BGP peer config like making a phone call - you need the phone number (neighbor IP) and to know who you're calling (AS number); a password to unlock your phone and a contact name (description) are nice but optional.
