In the early Vedic society, different groups had specific roles and responsibilities. Let's examine each group and their corresponding roles:

i) Aryas - Performed rituals:
The Aryas were a group of people who played a significant role in the early Vedic society. They were responsible for performing various rituals and ceremonies. These rituals were considered essential for maintaining harmony and balance in the universe and were performed to please the gods. The Aryas had a deep understanding of the rituals and their significance. They performed these rituals with great devotion and were considered as experts in conducting religious ceremonies.

ii) Brahmins - Composed hymns:
The Brahmins were a social and intellectual elite in the early Vedic society. They belonged to the highest caste, known as the priestly caste. One of their primary responsibilities was to compose hymns and chants that were recited during the rituals and ceremonies. These hymns, called the Vedas, were considered sacred and were believed to have divine origins. The Brahmins were not only responsible for composing these hymns but also for preserving and transmitting them orally from generation to generation.

iii) Vish - People or community:
The term "Vish" refers to the general population or community in the early Vedic society. They were the common people who did not belong to the priestly or warrior caste. The Vish played a vital role in supporting the religious and social structure of the society. They participated in the rituals and ceremonies conducted by the Aryas and Brahmins, seeking blessings and guidance from the gods. The Vish also contributed to the economic activities and provided resources and labor required for the smooth functioning of the society.

iv) Dasyus - Maintained law and order:
The Dasyus were a group of people who were responsible for maintaining law and order in the early Vedic society. They were considered as the rulers or administrators who enforced rules and regulations. The Dasyus ensured that the society functioned smoothly and peacefully. They resolved conflicts, settled disputes, and maintained social harmony. They played a crucial role in keeping the society organized and ensuring that everyone abided by the established norms and regulations.

In conclusion, the correctly matched pair of groups and roles played in the early Vedic society are:

- Aryas: Performed rituals
