The correct option is (d).
Explanation
The Rigvedic religion was primarily ritualistic, focusing on the worship of natural forces personified as deities (such as Indra, Agni, and Varuna). The central mode of worship was the performance of Yajnas (sacrifices), where Agni (Fire) acted as the intermediary carrying oblations from humans to the gods.
Statement-wise Analysis:
- Statement 1 is Correct: Dairy products were a staple of the Vedic diet and rituals. Offerings of ghee (clarified butter) and milk were fundamental to the sacrificial fire to appease the deities.
- Statement 2 is Correct: Agricultural produce was also offered. Grain, specifically barley (Yava), was commonly used in oblations during the sacrifices.
- Statement 3 is Correct: Animal sacrifice was practiced during the Rigvedic period. While many domestic rituals were simple, larger sacrifices often involved the offering of animals to the gods.
Key Takeaway:
Rigvedic worship did not involve image worship or temples; instead, it relied on the recitation of prayers and the offering of ghee, grain, and animals into the sacrificial fire.
