Which of the following pairs are correctly matched ? I. Idukki ... Thermal power station II. Sabarigiri ... Hydro-electric project III. Ghatprabha ... Irrigation project IV. Ramganga ... Multipurpose project Select the correct answer by using the codes given below : Codes :

Idukki is a large hydroelectric project on the Periyar River and not a thermal power station, so statement I is incorrect [1]. Sabarigiri is a known hydroelectric project in Kerala, making statement II correct. Ghatprabha refers to the Ghataprabha irrigation/reservoir project used primarily for irrigation, so statement III is correct. The Ramganga scheme is treated as a multipurpose river project (covering irrigation, power and related uses), so statement IV is also correct. Consequently, II, III and IV are correctly matched while I is not; option 1 (II, III and IV) is the right choice.
