The correct option is A Civil court
Section 10 of the MRTP Act,1969 empowers the MRTP Commission to enquire into monopolistic or restrictive trade practices upon a reference from the Central Government or upon its knowledge or on the information. The Commission shall, for any inquiry under the Act, have the same powers as are vested in a civil court under the Civil Procedure Code while trying a suit, in respect of certain matters. Hence, Option A is correct. The rest of the courts are vested with more power, hence, incorrect.
