A land-use classified raster with nine different classes needs to be resampled from 10 x 10 m to 30 x 30 m cell size. The resample tool must be used, and the land classes must be preserved.
For categorical (classified) rasters such as land-use data, Nearest Neighbor interpolation must be used during resampling. This technique preserves the original class values without introducing fractional or interpolated values.
Cubic (Option A) and Bilinear (Option B) are interpolation methods suited for continuous data (elevation, temperature, etc.), but will distort categorical data.
Therefore, the correct answer is C.
