Isohyets:
- It is a line joining points of equal rainfall for a given interval or Isohyets are contours of equal precipitation analogous to contour lines on a topographic map.
- In the isohyetal method, precipitation values are plotted at their respective stations on a suitable base map, and isohyets are drawn to create an isohyet map.
∴ In isohyets, the line joining points on a map where the amount of precipitation recorded in a given period is the same.

Explanation:
The correct answer is option 'D', isohyet. Let's understand what an isohyet is and why it is the correct term for a contour of constant rainfall.
Definition of Isohyet:
An isohyet is a line on a map that connects points of equal or constant rainfall. It is derived from the Greek words "iso" meaning equal and "hyetos" meaning rain. Isohyets are used to represent the spatial distribution of rainfall across a given area.
Reasons why isohyet is the correct term:
1. Isopleth: An isopleth is a line on a map that connects points of equal value of a particular variable, such as temperature or elevation. While rainfall can be considered a variable, the term isopleth is not specifically used for rainfall contours. It is a more general term used for any variable. Therefore, option 'A' is not the correct answer.
2. Isochrone: An isochrone is a line on a map that connects points that can be reached in the same amount of time. It is commonly used in transportation planning to represent travel times. Isochrones are not specifically related to rainfall, so option 'B' is not the correct answer.
3. Isopluvial: The term isopluvial is not commonly used in the field of meteorology or hydrology to describe contours of rainfall. It is not a widely recognized term, so option 'C' is not the correct answer.
4. Isohyet: Isohyet is the correct term used to describe contours of constant rainfall. It specifically refers to lines connecting points of equal rainfall. These contours are commonly used in rainfall analysis, hydrological modeling, and weather forecasting. Therefore, option 'D' is the correct answer.
In conclusion, the correct term for a contour of constant rainfall is isohyet. It is used to represent the spatial distribution of rainfall across an area, and it is derived from the Greek words meaning equal rain.
