Step 1: Understanding the SDG themes.
Each SDG (Sustainable Development Goal) has specific targets associated with global challenges like water, health, and consumption.
Step 2: Matching the SDGs.
SDG 6 focuses on clean water and sanitation (\(s\)).
SDG 11 emphasizes sustainable cities and communities (\(r\)).
SDG 3 is related to good health and well-being (\(p\)).
SDG 12 addresses responsible consumption and production (\(q\)).
Step 3: Conclusion.
Thus, the correct match is: i - s, ii - r, iii - p, iv - q.
