Step 1: Recall Mauryan contributions.
The Mauryan Empire (321–185 BCE) under rulers like Chandragupta and Ashoka produced some of the most significant archaeological monuments in India.
Their remains include stone pillars, inscriptions, stupas, and caves.
Step 2: Analyze each element.
- Pillars and Caves: Correct. Polished stone Ashokan pillars and Barabar Caves are examples.
- Inscriptions and Rock Edicts: Correct. Ashoka spread Buddhist messages through inscriptions.
- Stupas: Correct. The Mauryas built many stupas like Sanchi and Bharhut.
- Brahminical Temples: Incorrect, since Mauryan art was largely Buddhist, not temple-oriented.
Step 3: Elimination.
Options including (D) Brahminical Temples are wrong. Thus, only (C) remains.
Step 4: Conclusion.
Hence, the correct answer is (C) A, B and C only.
