What subway do you take to the General Post Office at 271 Cadman Plaza East in Brooklyn?

Which subway route to take depends on where you're coming from. You can take the F (of the B-D-F-M, the orange line) to York Street, the A or C (of the A-C-E, the blue line) to High Street, the 2 or 3 (of the 1-2-3, the red line) to Clark Street, the N or R (of the N-R-Q, the yellow line) to Court Street, or the 4 or 5 (of the 4-5-6, the dark green line) to Borough Hall.

I have listed the stations in descending order. Each one is further south than the last (i.e., the F to York Street is the furthest north, then the A or C to High Street-Brooklyn Bridge, then the 2 or 3 to Clark Street, etc.)
