Let’s check all the options

• Option (A) Underground tanks or tankas - These are traditional water-harvesting techniques used in arid and semi-arid regions of Rajasthan, Gujarat and Madhya Pradesh. They are built inside the main house or courtyard to store drinking water. They are not suitable for hill and mountainous regions. So, this is incorrect

• Option (B) Inundation channels - These are traditional water-harvesting techniques used in flood-prone regions of Bihar, West Bengal and Assam. They are channels that divert the flood water to nearby fields or storage structures. They are not suitable for hill and mountainous regions. So, this is incorrect

• Option (C) Diversion channels like ‘guls’ or ‘kuls’ - These are traditional water-harvesting techniques used in hill and mountainous regions of western Himalayas . They are channels that divert water from natural streams or springs to nearby fields or villages. They are suitable for hill and mountainous regions. So, this is correct

• Option (D) Rooftop rainwater harvesting systems - These are modern water-harvesting techniques used in urban and rural areas of various regions of India. They collect rainwater from rooftops and store it in tanks or recharge it into groundwater. They are not specific to hill and mountainous regions. So, this is incorrect
