An IFR flight plan requires an alternate aerodrome. The alternate has only an NDB approach with an MDA of 800 ft. Under AIP ENR 1.1, the minimum forecast ceiling at the alternate at ETA is approximately:

• A.MDA exactly = 800 ft ceiling minimum
• B.MDA + 200 ft = 1,000 ft ceiling minimum
• C.VMC ceiling (1,500 ft) regardless of approach type
• D.MDA + 400 ft = 1,200 ft ceiling minimum
