Question Analysis
This question involves identifying the most electronegative element in Group 16 using periodic trends. The main focus is on the relationship between atomic size and electronegativity within a group.

Key Concept Explanation
Electronegativity decreases down a group due to increasing atomic radius and shielding effect.
The smallest atom in a group (topmost element) has the strongest attraction for bonding electrons and thus the highest electronegativity.

Step-by-Step Solution
1. List Group 16 elements in order (top to bottom): O, S, Se, Te, Po.
2. Apply the group trend: electronegativity decre...
