Hint:
It is the largest dam of Maharashtra. It is a complex project with four dams. It is 103 meters in height and 807 meter long rubble concrete dam.

Complete answer:
Sardar sarovar - The Sardar Sarovar Project is one of the largest water resources projects. The project covers four major states of India - Maharashtra, Madhya Pradesh, Gujarat and Rajasthan. The dam's spillway discharging capacity (30.7 million cusecs) will be third in the world.

The dam will be India's third highest concrete dam (163 m), the first two are Bhakra (226 m) in Himachal Pradesh and Lakhwar (192 m) in Uttar Pradesh. This is not the largest hydroelectric power project of India. Thus this option is incorrect.

Koyna - The koyna hydroelectric project is the largest completed hydroelectric Power plant in india. Koyna Sami's built on the koyna river in sangli district. It was built in 1863. This is the largest dam in Maharashtra. It has a water capacity of 1878 TMC and produces 1920 megawatt power. This is the largest completed hydroelectric project of India. Thus this option is correct

Bhakra Nangal - The Bhakra-Nangal dam, which is about 207.26 m in height, was the second highest dam in Asia after the Tehri dam. It was the only dam in Asia to have a capacity to produce 1500 MW of electricity in 2013. The Bhakra Nangal Dam is 518.25 (1,700 ft) in length and 9.1 m (30 ft) in width.

Nathpa jhakri - The Nathpa Jhakri Hydroelectric Project is located on the Sutlej River, on the Hindustan Tibet Road in Himachal Pradesh. The project was commissioned in May 2004.
Nathpa Jhakri Hydropower is the fourth largest hydroelectric plant in the country and its station capacity is 1500 MW. Allotment of power from this plant is in North Indian states Haryana, HP, Punjab, Jammu and Kashmir, Rajasthan, Uttar Pradesh, Uttarakhand and Happens to all the cities of Delhi and Chandigarh.

Therefore, the correct answer is B
