The agrahara in early India refers to the practice of granting a village or land to Brahmins. Option 1 is correct because it accurately presents this concept. Brahmins were part of the highest social class in ancient India, known as the priestly or intellectual class. They were revered for their knowledge of scripture, religious rituals, and spiritual guidance.

It was a common practice for rulers, landlords, or wealthy individuals to grant agraharas to Brahmins. Agraharas were usually self-sustaining villages or parcels of land specifically designated for the support of Brahmins. The purpose of these grants was to provide the Brahmins with the resources they needed to undertake religious and intellectual pursuits without having to worry about their livelihood.

Agraharas typically had agricultural land, livestock, and other resources that provided the necessary sustenance for Brahmins. The Brahmins, in turn, would perform religious ceremonies and rituals, provide intellectual guidance, and impart spiritual knowledge to the community.

Option 2, mentioning the garland of flowers of Agar, and options 3 and 4, referring to grants of land to officers and soldiers or settlements by Vaishya farmers, are not related to the concept of agrahara and therefore incorrect.
