Builder X plans to renovate Sundervan Society following a specific sequence of steps shown in a Data Flow Diagram (DFD). According to the process, at which point should the builder have obtained legal permission from the concerned authority for the renovation work?

Accepted Answer

**Solution:**

1. According to the given Data Flow Diagram, the renovation process involves several steps including asking for permission from the people of the society, asking them to vacate their houses, hiring architects, and starting renovation.

2. Legal permission from the concerned authority is a prerequisite before any physical action such as vacating the building or renovation can begin.

3. The builder should have obtained legal permission **before** asking the people of the society to vacate their houses, as vacating involves physical displacement and legal implications.

4. Obtaining permission after hiring architects or after asking people to vacate would be too late in the process.

5. Therefore, the correct step to take legal permission is **before asking the people of the society to vacate their houses**.

**Answer:** (b) Before asking the people of the society to vacate their houses.
