Question Analysis
This question involves comparing bond polarity based on electronegativity differences. The main focus is on calculating ΔEN for each bond and identifying the largest value.

Key Concept Explanation
Bond polarity is directly proportional to the electronegativity difference (ΔEN) between bonded atoms. A larger ΔEN means more unequal electron sharing and greater bond polarity.

Step-by-Step Solution
1. Recall electronegativity values: H = 2.2, C = 2.5, N = 3.0, O = 3.5, F = 4.0
2. Calculate ΔEN for each bond:
A. |2.5 - 2.2| = 0.3
B. |3.5 - 2.2| = 1.3
C. |3.0 - 2.2| = 0.8
D. ...
