Maximum airspeed below Class B airspace...what is "...minimum safe airspeed..."

Regarding these two sub-paragraphs:  

(c) No person may operate an aircraft in the airspace underlying a Class B airspace area designated for an airport or in a VFR corridor designated through such a Class B airspace area, at an indicated airspeed of more than 200 knots (230 mph).

(d) If the minimum safe airspeed for any particular operation is greater than the maximum speed prescribed in this section, the aircraft may be operated at that minimum speed.

What is the "minimum safe airspeed for any particular operation?"  If my minimum clean speed is 220, would I be authorized to fly 220 KIAS below Class B, or must I keep flaps out and fly at 200 KIAS?

The FAA answered this exact question ten years ago.

See the next to last paragraph on page 2.  Unless ATC says otherwise, if you can configure the aircraft to be safely flown at/below 200 KIAS in that airspace, you must do so.
