What is the required VFR cloud clearance for Class B airspace?

The required VFR cloud clearance for Class B airspace is indeed 3 statute miles of visibility and clear of clouds. This regulation ensures that pilots have sufficient visibility to navigate safely and maintain visual separation from other aircraft, as Class B airspace is typically found around the busiest airports, where air traffic is more congested. The requirement to be clear of clouds allows for better situational awareness and safer operating conditions, reducing the chances of inadvertent encounters with other aircraft or ground obstructions.

In contrast, the other options do not align with the specific regulations for Class B airspace. For example, 1 statute mile visibility without cloud clearance may not provide enough visual reference in such busy airspaces, while visibility with specific distances above and below clouds is more applicable to other classes of airspace. Similarly, different visibility and cloud clearance requirements would be found in Class G or E airspace but not in Class B.
