What are the lowest authorized ILS minimums related to CAT II approaches?

The lowest authorized ILS minimums for CAT II approaches are defined primarily by the Decision Height (DH) and the Runway Visual Range (RVR). For a CAT II approach, the minimums stipulate that the Decision Height is 100 feet and the RVR requirement is 1,200 feet. This particular combination allows for approaches where the aircraft can descend to a decision height of as low as 100 feet above the runway while still requiring a minimum visibility of 1,200 feet to land safely.

Understanding these minimums is crucial because they set the standards for operations in lower visibility conditions and ensure safety while allowing more flexibility for landings. Other choices present different configurations of DH and RVR that do not align with the standards set for CAT II approaches, making choice A the only correct representation of the regulatory requirements for such operations.
