Concept:
Raster data represents continuous phenomena such as elevation, temperature, and satellite imagery, whereas discrete features like land parcels are best represented using vector data.
Step 1: Classify the data types.
\[
\boxed{
\begin{aligned}
\text{Raster} &\rightarrow \text{Elevation, Temperature, Imagery}\\
\text{Vector} &\rightarrow \text{Land parcels, Roads, Buildings}
\end{aligned}
}
\]
Step 2: Identify the exception.
Hence,
\[
\boxed{\text{Land parcels are represented using vector data, not raster data}.}
\]
Therefore, the correct option is
\[
\boxed{(C).}
\]
