Regarding BSE stock

Anyone please describe me the different grades in BSE like XC,XD,XT,Z,ZP

BSE has grouped stocks into categories based on various parameters.
Z group includes stocks which have failed to comply with the listing requirements of the exchange.
the XC, XD, XT group contains stocks which have low to moderate market cap and don’t contribute much to the trading turnover on the exchange. Stocks in this group require a lot of oversight and monitoring.
