The correct option is 2 and 3 only because the Banks Board Bureau (BBB), established in 2016, is tasked with recommending appointments for heads of Public Sector Banks (PSBs) and assisting in the formulation of strategies and capital-raising plans. However, the Chairman of the BBB is not the Governor of the Reserve Bank of India (RBI); instead, it is an independent position held by a non-RBI official. This distinction is critical as it underscores the BBB's role as an autonomous body aimed at enhancing governance and accountability in PSBs, rather than functioning under the RBI's direct control.
