Question Analysis
This question tests the student's understanding of periodic trends in electronegativity and their ability to compare the electronegativity of different elements.

Key Concept Explanation
Electronegativity increases across a period from left to right and decreases down a group from top to bottom. The Pauling scale provides a reference for comparing the relative electronegativities of elements.

Step-by-step Solution
1. Identify the position of sulfur (S) and chlorine (Cl) in the periodic table.
2. Sulfur (S) is in period 3, group 16, with an electronegativity of 2.58.
3. Chlorine (Cl) is in period 3, group 17, with an electronegativity of 3.16.
4. Compare the positions of the given options:
Phosphorus (P) is in period 3, group 15, with an electronegativity of 2.19.
Selenium (Se) is in period 4, group 16, with an electronegativity of 2...
