Answer

Explanation:

Step1: Recall polarity concept

Polarity is due to electronegativity difference.

Step2: Analyze electronegativities

Oxygen is highly electronegative. Hydrogen has lower electronegativity. Nitrogen is also electronegative but less than oxygen.

Step3: Evaluate each bond

Bond A (O - H): Large electronegativity difference (O is 3.44, H is 2.20), highly polar.
Bond B (C - H): Small electronegativity difference (C is 2.55, H is 2.20), less polar.
Bond C (C - C): Same atoms, electronegativity difference is 0, non - polar.
Bond D (N - H): Electronegativity difference (N is 3.04, H is 2.20), polar but less than O - H.
