The correct answer is A. Kangra.
The percentage of Scheduled Tribes (STs) population in Kangra district is 1.6%, which is the lowest among all the districts of Himachal Pradesh. The percentage of STs population in Hamirpur district is 2.3%, in Kullu district is 3.2%, and in Kinnaur district is 4.1%.
The STs are a group of people who are considered to be indigenous to India. They are also known as tribals or adivasis. The STs are a diverse group of people with their own unique cultures and languages. They are found in all parts of India, but they are concentrated in the hilly and tribal areas of the country.
The STs have been historically marginalized and discriminated against. They have been denied access to education, healthcare, and other basic services. They have also been subjected to violence and exploitation.
In recent years, there has been a growing awareness of the rights of the STs. The government has taken some steps to improve the lives of the STs, but much more needs to be done.
The STs are an important part of the Indian society. They have a rich culture and a unique way of life. It is important to respect their rights and to ensure that they have equal opportunities in life.
