Which of the following statements best describes a harijan?

a. A Pakistani supporter of the Soviet Union.

c. A member of the untouchable caste.

b. A member of the communist party.

d. A Pakistani-Bangladesh mediator.

A harijan is the name that Mahatma Gandhi used for people who are most commonly known as dalits, and the dalits are untouchables - so the correct answer is c. A member of the untouchable caste.

Now this name is considered condescending and it's not longer used.
