Explanation:

- Option 1: Self Honor Groups

- This is not the commonly recognized term for SHGs.

- "Self Honor" implies a focus on personal pride, which isn't the main aim of SHGs.

- Option 2: Self Help Groups

- The correct expansion of SHG.

- These groups are local associations where members support each other, often focusing on improving financial literacy and mutual aid.

- Option 3: Secondary Help Groups

- This term isn't used widely or known in the context of SHGs.

- "Secondary" suggests a supporting role rather than being primary, which is misleading.

- Option 4: Stand Helping Groups

- This option is not recognized as a definition of SHGs.

- "Stand Helping" isn't a conventional term used for these groups.
