D.    Reduce the number of nodes in a broadcast domain.

Answer: D
Explanation:
VLANs provide the following advantages:
* VLANs enable logical grouping of end-stations that are physically dispersed on a network. …
* VLANs reduce the need to have routers deployed on a network to contain broadcast traffic. …
* Confinement of broadcast domains on a network significantly reduces traffic.
By confining the broadcast domains, end-stations on a VLAN are prevented from listening to or receiving broadcasts not intended for them. Moreover, if a router is not connected between the VLANs, the end- stations of a VLAN cannot communicate with the end-stations of the other VLANs.
