Step 1: Concept
Bond angles in molecules.
Step 2: Meaning
Matching common molecular structures to their bond angles.
Step 3: Analysis
$SO_2 \approx 119.5^{\circ}$ (IV). $NO_2 \approx 134^{\circ}$ (I). $O_3 \approx 117^{\circ}$ (II). $S_8$ (ring structure) $\approx 107^{\circ}$ (V).
Step 4: Conclusion
Correct matching is A-IV, B-I, C-II, D-V.
Final Answer: (A)
