Concept:
Social problems are complex and multidimensional. Their analysis generally requires understanding their interrelated nature, multiple causes and relative character across societies.
The Invisible Hand is an economic concept introduced by Adam Smith to explain how individual self-interest can lead to efficient market outcomes. It is not a sociological approach for solving social problems.
Step 1: Examine each option.
• [(A)] Invisible Hand is an economic concept related to market mechanisms, not an approach to solving social problems.
• [(B)] Multiple-factor approach recognises that social problems arise due to several interacting causes.
• [(C)] Interrelatedness explains that one social problem is often linked with others.
• [(D)] Relativity means that the nature of social problems varies across societies, cultures and time periods.
Therefore,
\[
\boxed{
\text{Invisible Hand is not considered an approach for solving social problems.}
}
\]
Hence,
\[
\boxed{\text{Correct Answer}=(A)}
\]
