A wet vent serves a bathroom group. The key characteristic of a wet vent is that:
a.It carries only air, never any drainage
b.It must be a separate pipe from all fixtures
c.It vents only the toilet
d.A single pipe serves as both the drain for one fixture and the vent for another
Explanation
In a wet vent, a section of pipe acts simultaneously as a drain for one fixture and as the vent for one or more other fixtures in the same bathroom group, sized larger to carry both functions. It does carry drainage, is not a fully separate vent, and is not limited to venting the toilet.
