A Network 172.16.1.32 mask 255.255.255.224
B Network 172.16.1.0 0.0.0.255
C Network 172.16.1.32 255.255.255.224
D Network 172.16.1.33 mask 255.255.255.224
E Network 172.16.1.32 mask 0.0.0.31
F Network 172.16.1.32 0.0.0.31

Explanation

To advertise that loopback in Cisco BGP, the network statement must specify the exact prefix present in the routing table and use the mask keyword with the subnet mask. The interface address 172.16.1.33 with mask 255.255.255.224 belongs to network 172.16.1.32/27, so the correct command is network 172.16.1.32 mask 255.255.255.224.
