Which of the following best explains why the nineteenth-century social reform movements are often described as middle-class reform movements?

Most of the reformers belonged to the newly emerging western-educated Indian middle class.

The correct answer is Option 2: Most of the reformers belonged to the newly emerging western-educated Indian middle class.

The nineteenth-century social reform movements are called middle-class reform movements because many of their leaders emerged from the newly educated Indian middle class. Their ideas combined democratic values with a concern for social reform, particularly women's rights.

NCERT: "The women’s question arose in modern India as part of the nineteenth century middle class social reform movements. The nature of these movements varied from region to region. They are often termed as middle class reform movements because many of these reformers were from the newly emerging western educated Indian middle class. They were often at once inspired by the democratic ideals of the modern west and by a deep pride in their own democratic traditions of the past. Many used both these resources to fight for women’s rights. We can only give illustrative examples here. We draw from the anti-sati campaign led by Raja Rammohun Roy in Bengal, the widow remarriage movement in the Bombay Presidency where Ranade was one of the leading reformers, from Jyotiba Phule’s simultaneous attack on caste and gender oppression, and from the social reform movement in Islam led by Sir Syed Ahmed Khan.
