Grid North on a topographic map is defined as the direction along what?

Grid North is the direction along the map’s grid lines, specifically the vertical grid lines that run north–south on the map. This orientation comes from the map’s coordinate grid and projection, not from where true north or magnetic north happen to be in the real world. True North points to the geographic north pole, Magnetic North to the magnetic pole, and the Prime Meridian is just the zero longitude line used for global coordinates. So Grid North aligns with those vertical grid lines on the map, making it the correct choice.
