The correct option is C) 2 4 1.
– **Isobars:** Lines connecting points of equal atmospheric pressure on a weather map. (Match with 2)
– **Isohels:** Lines connecting points that receive equal amounts of sunshine duration over a given period. (Match with 4)
– **Isochrones:** Lines connecting points where a phenomenon occurs simultaneously or which are reached at the same time (e.g., lines of equal travel time from a specific point). (Match with 1)
– Lines of equal salinity are called isohalines (Option 3).
Iso- lines (or isolines) are graphical representations used on maps and charts to connect points of equal value for a specific variable. Examples include isotherms (equal temperature), isohyets (equal rainfall), isobaths (equal depth of water), contours (equal altitude), etc.
