Question Analysis
This question assesses the understanding of bond type correlation based on the electronegativity difference (ΔEN) between two elements.

Key Concept Explanation
A polar covalent bond forms when the ΔEN between two atoms is between 0.4 and 1.7. The pair of elements that meets this criterion is oxygen (O) and hydrogen (H).

Step-by-step Solution
1. Determine the electronegativity values for each pair of elements.
2. Calculate the ΔEN for each pair.
3. Identify the pair with a ΔEN between 0.4 and 1.7.
4. Oxygen (O) has an electr...
