Which airspace states that VFR traffic is not separated?

• A. Class B
• B. Class D
• C. Class E
• D. Class G

Answer: (B)

VFR traffic is not separated in airspace where there is no ATC service at all—uncontrolled airspace. In this environment every pilot is responsible for maintaining separation from other aircraft using see-and-avoid and their own judgement, because ATC does not provide separation services for VFR.

Among the options, the one that describes this scenario is the uncontrolled airspace. In the other, controlled airspaces, ATC provides separation services (at least for IFR traffic, and often gives advisories or traffic information to VFR). So the statement that VFR traffic isn’t separated best fits the uncontrolled airspace rather than the controlled ones.
