Show Hint
Remember the adjective order shortcut:
\[
\text{OSASCOMP}
\]
(Opinion, Size, Age, Shape, Colour, Origin, Material, Purpose)
Also check the article:
\textbf{a} before consonant sounds
\textbf{an} before vowel sounds
Step 1: Recall the standard order of adjectives in English.
The common order is:
\[
\text{Opinion} \rightarrow \text{Size} \rightarrow \text{Age} \rightarrow \text{Colour} \rightarrow \text{Origin} \rightarrow \text{Material} \rightarrow \text{Purpose}
\]
Step 2: Classify the adjectives given. old — age
blue — colour
German — origin
Step 3: Arrange them in the correct order.
\[
\text{old} + \text{blue} + \text{German} + \text{car}
\]
Also, since \emph{old} begins with a vowel sound, the correct article is an.
Step 4: Match with the given options.
This sequence matches option (C).
Hence, the correct answer is
\[
\boxed{\text{an old blue German}}
\]
