Concept:
The doctrine of Dharmacakra Pravartana refers to the Buddha's “Turning of the Wheel of Dharma.” Mahāyāna traditions describe multiple turnings associated with different teachings and locations.
Step 1: Identifying the First Turning.
E. First --- Sāranātha
The First Turning occurred at Sarnath where the Buddha delivered the Dhammacakkappavattana Sutta to the five ascetics, explaining the Four Noble Truths and the Middle Path.
Step 2: Identifying the Second Turning.
C. Second --- Gṛdhakūṭa
The Second Turning is associated with Gṛdhakūṭa (Vulture Peak) at Rājagṛha, where Prajñāpāramitā and Śūnyatā teachings were expounded.
Step 3: Rejecting incorrect places.
• Kurukṣetra has no connection with Dharmacakra Pravartana.
• Delhi is unrelated to the canonical turnings.
• Rajasthan is not counted among the classical turning sites.
Step 4: Final Conclusion.
The correct places are:
\[
\boxed{C \text{ and } E}
\]
Therefore, Option (3) is correct.
