Step 1: Review the Stratigraphic Units and their Corresponding Ages.
- The Barail Formation is associated with the Miocene age in the geological time scale, not the Eocene.
- The Mahadek Formation is associated with the Eocene period, not Oligocene.
- The Naredi Formation is correctly associated with the Eocene age.
- The Dalmia Puram Formation is associated with the Paleocene, but not in this case.
Thus, the correct answer is (C) Naredi Formation – Eocene.
Final Answer:
\[
\boxed{\text{Naredi Formation – Eocene}}
\]
