In September 2013, the Reserve Bank of India (RBI) implemented a significant policy update to foster broader banking service dissemination throughout India. Previously, commercial banks were required to obtain the RBI's prior authorization for establishing new branches, particularly in metropolitan and urban centers. To advance financial inclusion and enhance banking accessibility, the RBI eased this requirement, permitting financially stable banks to inaugurate branches in major cities without needing specific approval for each new location. This initiative was integrated within wider banking sector reforms designed to boost competition, extend reach, and improve customer service. The eased regulation enabled banks to react more swiftly to market needs and establish branches where required, thereby reinforcing their operational footprint. Consequently, the appropriate answer is option (A) September 2013.
