Answer - A - Very small cell coverage overlap cause issues associated with roaming.

Key Takeaway: Roaming problems occur if there is very small overlap in cell coverage. Very small overlap creates a roaming dead zone and connectivity may even be lost temporarily. If two RF cells have too much overlap, a station may stay associated with its original AP and not connect to a second access point even though the station is directly underneath the second access point.
