Which of the following is known as horizon of eluviation?

The E horizon, the zone of greatest eluviation, is very leached of clay, chemicals, and organic matter.  Because the chemicals that color soil have been leached out, the E layer is very light in color.  It usually occurs in sandy forest soils in high rainfall areas. T he eluvial horizon refers to a light-colored zone located (depending on context and literature) either at the lower part of the A horizon (symbol: Ae) or within a distinct horizon (E horizon) below the A.
