The correct option is "Only two" because statements 2 and 3 are accurate in the context of SHGs: each member collectively guarantees the loan for any individual, fostering a sense of responsibility and mutual support, and the Regional Rural Banks and Scheduled Commercial Banks play a significant role in providing financial support to SHGs. However, statement 1 is incorrect; while the SHG movement has received strong support from the State Bank of India, it was actually initiated through NABARD (National Bank for Agriculture and Rural Development) in the 1980s to promote self-help among rural women, not just by microcredit from SBI. This clarification highlights the need to understand key institutions and their correct roles in India's microfinance landscape, which is crucial for the UPSC examination focusing on socio-economic initiatives.
