The Deen Dayal Upadhyaya Grameen Kaushalya Yojana (DDU-GKY) focuses on:

Skill development for rural youth
Financial inclusion
Irrigation projects
Electrification of villages

The correct answer is: a) Skill development for rural youth.

The Deen Dayal Upadhyaya Grameen Kaushalya Yojana (DDU-GKY) is a government-sponsored skill development program for rural youth in India. The program was launched in 2014 with the goal of providing training and employment opportunities to rural youth. The program offers a variety of training courses in different sectors, such as agriculture, manufacturing, and services. The program also provides financial assistance to trainees to help them cover the cost of training and living expenses.

The DDU-GKY has been successful in providing training and employment opportunities to rural youth. The program has trained over 10 million youth and helped them find employment. The program has also helped to reduce poverty and improve the lives of rural youth.

Option b) is about financial inclusion, which is the process of bringing the unbanked and underbanked into the formal financial system. Option c) is about irrigation projects, which are projects that are designed to provide water for irrigation. Option d) is about electrification of villages, which is the process of providing electricity to villages.
