Concept:
A Geographic Information System (GIS) is an integrated system consisting of hardware, software, data, people, and methods.
These components work together to capture, store, analyze, manage, and display geographic information.
Step 1: Recall the components of GIS.
The five fundamental components are
\[
\boxed{
\begin{aligned}
&\text{Hardware}\\
&\text{Software}\\
&\text{Data}\\
&\text{People}\\
&\text{Methods}
\end{aligned}
}
\]
Step 2: Evaluate the options.
Options containing only one component are incomplete.
The only option containing multiple essential GIS components is
\[
\boxed{\text{Hardware, Software and Data}.}
\]
Therefore, the correct option is
\[
\boxed{(D).}
\]
