Concept:
A mural is a painting made directly on a wall, ceiling, cave surface, temple wall, or any large permanent architectural surface.
Famous Indian mural traditions include:
\[
\text{Ajanta murals, Sittanavasal murals, Brihadeshwara temple murals}
\]
Step 1: Check Sittanavasal.
Sittanavasal is famous for ancient mural paintings.
The paintings are found on cave surfaces and are related to Jain themes.
So, Sittanavasal is a mural site.
\[
\text{Sittanavasal} \Rightarrow \text{Mural}
\]
Step 2: Check Ajanta.
Ajanta is one of the most famous mural painting sites in India.
The Ajanta cave paintings are painted on cave walls and ceilings.
So, Ajanta is also mural.
\[
\text{Ajanta} \Rightarrow \text{Mural}
\]
Step 3: Check Brihadeshwara Temple.
Brihadeshwara Temple at Thanjavur is famous for Chola period murals.
These paintings are found on temple walls.
So, Brihadeshwara Temple is also associated with murals.
\[
\text{Brihadeshwara Temple} \Rightarrow \text{Mural}
\]
Step 4: Check Prajnyaparamita.
Prajnyaparamita is mainly associated with Buddhist manuscript tradition.
It is not a mural painting site like Ajanta or Sittanavasal.
Therefore, Prajnyaparamita is the one which is not mural.
Hence, the correct answer is:
\[
\boxed{\text{(C) Prajnyaparamita}}
\]
