Question Analysis
This question involves identifying the most electronegative atom within a covalent compound. The main focus is on applying known electronegativity values to specific elements in a molecule.

Key Concept Explanation
Electronegativity is an intrinsic property of an atom, not dependent on the compound it is part of.
Oxygen (EN = 3.5) has a higher electronegativity than sulfur (EN = 2.5) because it is higher in Group 16 (smaller atomic radius, stronger nuclear attraction for valence electrons).

Step-by-Step Solution
1. Recall the electronegativity values of S and O: O = 3.5, S = 2.5.
2. Compare the values: O has a higher electronegativity than S.
3. Eliminate incorrect options: C (values are unequal), D (electronegativity is a meas...
