a.It must be painted red only, with no strength requirement
b.It only needs to fully hide the hole from view
c.It must be removable by hand at any time and left unsecured for quick access
d.It must support at least twice the maximum intended load, be secured against displacement, and be marked to warn of the hazard

Correct: a compliant floor-hole cover must carry at least twice the maximum intended load (workers, equipment, materials), be secured so it cannot shift or be accidentally removed, and be marked (e.g., 'HOLE' or 'COVER') to warn workers. Color alone, hiding the hole, or leaving it loose for 'quick access' all fail the securing, strength, and marking requirements.
