The Correct Option is B
Solution and Explanation
In GIS, raster data represents spatial information in a grid format, where each grid cell or unit is called a pixel. The pixel is the smallest entity in raster data and holds values such as elevation, temperature, or land use. Each pixel represents a specific geographic area on the Earth's surface, and its size depends on the resolution of the raster image. A higher resolution means smaller pixels, offering finer detail.
Thus, the smallest entity of raster data is a Pixel.
