The correct option is A UNCITRAL Rules, 1980
As per section 61 which lies in Part III of the Act which deals with Conciliation, this Part shall apply to conciliation of disputes arising out of legal relationship, whether contractual or not and to all proceedings. Furthermore, this Part shall not apply where by virtue of any law for the time being in force certain disputes may not be submitted to conciliation. This provision is almost same to the pattern of Article 1 of the UNCITRAL Conciliation Rules, 1980. Further, preamble of the act also mentions that as UNCITRAL has adopted the UNCITRAL Conciliation rules 1980, the act also adopts the pattern of the rules.
