PART B: A. "The lovely gaze where every eye doth dwell" line 2
Explanation: The phrase "unfair which fairly doth excel" refers to how the process that made a face so beautiful, will destroy it eventually since everything is momentary. This statement is supported by line 2: "The lovely gaze where every eye doth dwell", which means that everybody loves to look at this person because of their stunning good looks. Both lines together refer to the fact that beauty is ephemeral.
