B- Vellalars weree a rural caste who took advantage of the new opportunities provided by British rule. 

Initially, jobs with the Company were monopolised by the Vellalars, a rural caste who took advantage of the new opportunities provided by British rule. With the spread of English education in the nineteenth century, Brahmins started competing for similar positions in the administration. Telugu Komatis were a powerful commercial group that controlled the grain trade in the city. Gujarati bankers had also been present since the eighteenth century. Paraiyars and Vanniyars formed the labouring poor.  The Nawab of Arcot settled in nearby Triplicane which became the nucleus of a substantial Muslim settlement. Mylapore and Triplicane were earlier Hindu religious centres that supported a large group of Brahmins. San Thome with its cathedral was the centre for Roman Catholics. All these settlements became part of Madras city. Thus the incorporation of many villages made Madras a city of wide expanse and low density. This was noticed by European travellers and commented on by officials.
