Selected Answer: B
To upgrade a router configuration file written in Network Layer Reachability Information (NLRI) format to the address-family identifier (AFI) format, and to make the router command-line interface (CLI) use only AFI commands, use the bgp upgrade-cli command in router configuration mode.

I've tried it in my lab and it does work:
(config)#router bgp 3351
(config-router)#bgp upgrade-cli
You are about to upgrade to the hierarchical AFI syntax of bgp commands
Are you sure? [yes]: yes
So, that's option B.
