Who among the following established the Depressed Classes Association?

Dr. B. R. Ambedkar

The correct answer is Option 3- Dr. B. R. Ambedkar

Dr. B. R. Ambedkar established the Depressed Classes Association (DCA) in 1930. The DCA was an organization dedicated to the upliftment of the depressed classes, who were later known as Scheduled Castes.

Ambedkar was a social reformer and politician who fought for the rights of Dalits. He believed that the depressed classes needed to organize themselves and fight for their own rights. The DCA was one of the first organizations to be established for the purpose of uplifting the depressed classes.

The DCA played a significant role in the Indian independence movement. It helped to raise awareness of the plight of the depressed classes and to mobilize them to fight for their rights. The DCA also played a key role in the drafting of the Indian Constitution, which guaranteed equal rights to all citizens, regardless of caste or religion.

The DCA was eventually dissolved in 1956, after Ambedkar converted to Buddhism and established the Republican Party of India. However, the DCA's legacy continues to this day. It is remembered as one of the most important organizations in the fight for the rights of Dalits.
