VTP version 3 adds a number of enhancements to VTP version 1 and VTP version 2:
• Support for a structured and secure VLAN environment (Private VLAN, or PVLAN)
• Support for up to 4k VLANs
• Feature enhancement beyond support for a single database or VTP instance
• Protection from unintended database overrides during insertion of new switches
• Option of clear text or hidden password protection
• Configuration option on a per port base instead of only a global scheme
• Optimized resource handling and more efficient transfer of information
I think B and E, because in VTPv3 you configure one only VTP Server able to add or delete VLANS (primary server)
Answer A: in another VTP versions you are allowed to configure switches in VTP off mode
