If the NCLT orders liquidation of corporate debtor, can the resolution professional who conducted CIRP be designated as a liquidator and conduct liquidation proceedings of the same corporate debtor?

Yes, but the final decision is that of the resolution professional if he/she wishes to continue
No, there is an absolute bar under the IBC where a resolution professional who conducted CIRP is not permitted to be a liquidator
Yes, but the NCLT needs to approve appointment of resolution professional as liquidator
No, because resolution professionals and liquidators are two different kinds of personnel with distinct skill sets
