Step 1: Understand the Assertion (A)
- Directive Principles are listed in Part IV of the Constitution and are not enforceable by courts (non-justiciable). So A is true.
Step 2: Understand the Reason (R)
- These principles guide the state in policymaking to ensure social and economic justice. So R is also true.
Step 3: Analyze the relationship
- The reason clearly explains why Directive Principles are non-justiciable — they are goals for the state rather than enforceable rights.
Therefore, both A and R are true and R correctly explains A.
