The correct options are
A Caste discrimination in schools
B Lack of transportation and less proximity to schools
D Poverty
The Dalits and Adivasis belong to the underprivileged sections of society. Hence, their children face discrimination in schools based on their caste and social background. Also, due to the lack of schools in rural areas, these children have to travel long distances to attend schools.
As citizens of this country, we need to work towards uplifting the underprivileged and ensure that everyone receives the fundamental right to education irrespective of their gender, caste and creed.
