Morphology
The meaning 'to draw lines or set boundaries' is directly derivable from combining 'mark' (to label or make a sign) with the particle 'off' which here signals separation or division; together they convey marking something as separate. This is a regular, compositional phrasal-verb pattern that a B1 learner who knows both constituents would readily understand.
Etymology
Mark off The phrasal verb mark off comes from drawing a line or putting tape to mark an area and set it off from the rest. That's why it means 'to separate' or 'to set a boundary'.
