The correct answer is D. Madhya Pradesh.
Kerala, Punjab, and Himachal Pradesh were all 100% electrified prior to the launch of the Saubhagya Scheme in 2015. Madhya Pradesh, on the other hand, was only 90% electrified at the time. The Saubhagya Scheme was a government initiative to provide electricity to all households in India, and it was successful in achieving its goal of 100% electrification by 2018.
Kerala was the first state in India to achieve 100% electrification, in 1997. Punjab followed suit in 2000, and Himachal Pradesh in 2005. Madhya Pradesh, on the other hand, lagged behind, and it was not until 2018 that the state achieved 100% electrification.
The Saubhagya Scheme was a major success, and it helped to improve the lives of millions of people in India. However, it is important to note that there are still some areas in the country that are not yet electrified. The government is working to address this issue, and it is hoped that all households in India will have access to electricity by 2022.
