What benefit does the "Vendor Directory" offer to event planners?

The "Vendor Directory" is a valuable resource for event planners as it provides a comprehensive listing of various suppliers and services that can be utilized for planning and executing events. By having access to this directory, event planners can easily find and connect with vendors who specialize in areas such as catering, audiovisual, decor, transportation, and more. This connection streamlines the planning process, allowing for efficient sourcing of services tailored to the specific needs of their events.

While options like access to attendee lists, information about permits and zoning laws, and databases of volunteer opportunities may have their own significance in the event planning process, they do not directly relate to the primary function of the "Vendor Directory," which is to facilitate connections with service providers. This makes option B the most relevant and beneficial choice for event planners seeking to enhance their sourcing capabilities.
