Why the Other Options Are Wrong
Option A: 12 in.
Choice A gives 12 in. Its specific error: 12 in. is not the OSHA ladder setup, extension, or access dimension cited here.
Option C: 30 in.
In general project requirements, 30 in. is the wrong selection for Stairway or ladder access: 30 in. is not the OSHA ladder setup, extension, or access dimension cited here.
Option D: 48 in.
The trap in D is 48 in. That selection is wrong because 48 in. is not the OSHA ladder setup, extension, or access dimension cited here.
