Question Analysis
This question involves multi-bond polarity comparison using periodic trend extrapolation, without provided electronegativity values. The main focus is on applying period electronegativity trends to rank bonds involving a common central atom.

Key Concept Explanation
Electronegativity increases across Period 2 (C < N < O < F). When bonded to the same atom (C), the electronegativity difference (ΔEN) increases as the bonded atom’s electronegativity increases. Larger ΔEN corresponds to greater bond polarity.

Step-by-Step Solution
1. Rank Period 2 elements by electronegativity: C (2.55) < N (3.04) < O (3.44) < F (4.0).
2. C...
