Separate aircraft operating above FL 410 by ____ feet.

Vertical separation above FL410 is 2,000 feet. RVSM reduces vertical separation to 1,000 feet only within the RVSM airspace band, which is between FL290 and FL410 inclusive, so above FL410 the standard separation rises back to 2,000 feet. The other options would either apply only inside the RVSM band (1,000 ft) or exceed the standard en route requirement (3,000 ft or 4,000 ft), which isn’t the rule above FL410.
