'Pakal Dul' hydroelectric power project is situated in

India's major Himalayan hydroelectric projects are named for the river valley they are built in, and are developed by central PSUs such as NHPC in partnership with state power agencies; correctly placing a project by state requires tracing its actual river and district, since several northern states host similar large-scale hydel schemes.

The Pakal Dul Hydroelectric Project (1,000 MW, storage-type) is being built on the Marusudar river near Dul village in Kishtwar district — a district that lies in Jammu and Kashmir, making Jammu and Kashmir the project's location.

Cross-check against the other options:

• Uttarakhand hosts Ganga-basin projects such as the Tehri Dam on the Bhagirathi, not any Chenab-tributary scheme.

• Jharkhand's rivers, the Damodar and the Subarnarekha, drain the Chotanagpur plateau, unrelated to the Himalayan Chenab system.

• Karnataka's major hydel capacity comes from peninsular rivers such as the Sharavathi, not from any Himalayan tributary.

• Only Jammu and Kashmir's Kishtwar district carries the Marusudar-Chenab basin project family, which includes Pakal Dul, Kiru, Kwar, and Ratle.
