Practice Exam Vent Connection
An architect is designing a single-family home with multiple bathrooms. The bathrooms will be plumbed in sequence, and circuit vent branching will be used to connect several lavatories. The builder of the home has asked the architect where the circuit vent branching should be connected, and the architect provides the builder with an isometric diagram to show those points of connection. Click on the area of the piping in the diagram to indicate where the circuit vent should connect.
CORRECT RESPONSE
Between the last fixture in sequence and next downstream fixture
Only the length of the drainage pipe between the last fixture in the sequence and the next downstream fixture can function as a point of vent connection for all three sinks.
I'm so lost with the question, could someone help me with the question?

The reason that the circuit vent connects into the last section of the drain line is because it is the most 'upstream' portion of the piping, which would allow proper circulation within the system and allow it to reach each fixture properly for the system to work as a whole.
