The right option is a. contour interval
The difference in elevation between the highest and lowest contour lines on a topographical map is called contour interval.
A contour interval is the vertical distance between the two contour lines (highest and lowest) in a topographical map. The contour interval is usually stated explicitly on the right-hand lower part in every map. 20 feet for a 1:24,000 map scale is the frequently used contour interval and different contour intervals is available for different maps.
Water, or H2O, is compounded using both hydrogen and oxygen. Hydrogen has a positive charge and oxygen has a negative charge. This helps the two compounds to interact with other chemicals such as salt and act as a solvent. The positive charge of sodium links up with oxygen's negative charge, and the positive charge of hydrogen links up with chlorine's negative charge. Oils are not polar however, and would not be able to dissolve, hence why during oil spills, it is a process to clean them up.
