Which option best interferes with the purpose of using gridlines on a large scale map
The option that best interferes with the purpose of using gridlines on a large-scale map would be "Making the gridlines extremely thick and prominent."
Gridlines are typically used on maps to provide a system of coordinates and aid in navigation. They allow users to easily locate and pinpoint specific locations on the map. However, if the gridlines are made extremely thick and prominent, they may overpower the other map features and make it difficult to read or interpret the information on the map. This could interfere with the purpose of using gridlines, as it may hinder the user's ability to accurately navigate and reference locations on the map.
