Answer: C) Sump pit
Explanation:
Wastewater from the house is allowed to flow out of places such as the bathroom or the kitchen sink through a floor drain.
This floor drain is connected to a sump pit which is typically located at the lowest point in the house (lowest point in basement) so that water can flow into it easier.
When the wastewater is released from the floor drain, it will flow into the sump pit. This water is in turn removed from the pit by a sump pump.
