Answer: Rarhi dialect
Notes: Chalitbhasa is the language of daily communication. It is based on the cultivated form of the dialects of Kolkata (Calcutta) and its neighbouring small towns on the Bhagirathi river. The pronouns and verbs of the Sadhubhasa are contracted in Chalitbhasa. The Standard Bengali language is emerged from the West-Central or Rarhi dialect spoken mainly in Kolkata and Nadia districts.
