Explanation:

- Sustainable Help for Growth:

- This option sounds like a program or initiative aimed at fostering sustainable development, but it's not a standard term in micro-finance.

- Surety and Help Group:

- This phrase suggests a mix of financial assurance and assistance, but it doesn't align with common micro-finance terminology.

- Sustainable Help Grant:

- Grants are typically non-repayable funds, but this option combines concepts usually not associated with micro-finance or SHG.

- Self Help Group:

- This is the correct option. SHG stands for Self Help Group. In micro-finance, SHGs are groups of individuals, typically in rural areas, who come together to pool their resources, save collectively, and access credit for personal or community projects.
