Question Analysis
This question tests the understanding of periodic trends in electronegativity and the ability to identify the element with the highest electronegativity.

Key Concept Explanation
Electronegativity generally increases across a period from left to right and decreases down a group. Among the given elements, chlorine (Cl) is the most electronegative because it is the farthest to the right and at the top of its group.

Step-by-step Solution
1. Identify the position of each element in the periodic table.
2. Compare their positions to determine which one is farthest to the right and at ...
