Option 'D' is correct. An imaginary line lying throughout the surface of the ground and preserving a constant inclination to the horizontal is known as a contour line. The inclination of the contour line to the horizontal is known as the contour gradient.
Contour lines are often used on topographic maps to show the shape and elevation of the land surface. They are drawn so that each line represents a constant elevation above sea level, and the spacing between the lines indicates the change in elevation. The difference in elevation between two adjacent contour lines is known as the contour interval.
Option 'A' is incorrect because "contour line" is the correct term for an imaginary line lying throughout the surface of the ground and preserving a constant inclination to the horizontal.
Option 'B' is incorrect because "horizontal equivalent" is not a term used in geography or cartography.
Option 'C' is incorrect because "contour interval" refers to the difference in elevation between two adjacent contour lines, not the line itself.

Contour Gradient
Contour gradient is an imaginary line lying throughout the surface of the ground and preserving a constant inclination to the horizontal.
Explanation:
- Contour lines: Contour lines are imaginary lines that connect points of equal elevation on the ground surface. They are represented on a topographic map by a series of different colors, symbols, and lines. They help to visualize the shape and relief of the land surface.
- Horizontal equivalent: Horizontal equivalent is a term used in surveying to describe the distance between two points on the ground surface measured along a horizontal line. It is also known as the horizontal distance or plan distance.
- Contour interval: Contour interval is the vertical distance between two adjacent contour lines on a topographic map. It is used to determine the slope of the land surface.
- Contour gradient: Contour gradient is the rate of change of the elevation of the ground surface along a contour line. It is expressed as a percentage or a ratio. For example, a contour gradient of 10% means that the ground surface rises or falls by 10 meters for every 100 meters of horizontal distance.
In conclusion, contour gradient is an important concept in topographic mapping and surveying. It helps to determine the slope of the land surface, which is important for various engineering and construction projects.
