The correct option is A sale or purchase of government securities
RBI's open market operation transactions
are carried out with a view to regulate liquidity in the economy, prices
of essential commodities and inflation. Open market operations refer to
sale and purchase of securities in the open market. During inflation,
securities are sold to reduce the liquidity of cash from the economy. As
a result, the money supply gets reduced and the inflation also gets
checked. Since, the infllation is corrected, prices of essential
commodities also starts to fall. Whereas, during deflation, securities are purchased from the market.
