Answer: D.
Explanation: VLANs let you segment a physical switch into multiple logical LANs, making adds/moves/changes easier by assigning a switch port to the appropriate VLAN. They reduce broadcast domain size (and increase the number of broadcast domains), do not inherently increase collision domains, and generally improve—not reduce—security.
