A) Attribute this to some overeating at the holidays.

This amount of weight over a short period should make one think of body fluid changes. You may consider a kidney problem or heart failure in your differential. The other reasons should be considered as well, but this amount of weight gain over a short period usually indicates causes other than excessive caloric intake. A rule of thumb for dieters is that an energy excess of 3500 calories will cause a 1-pound weight gain, if the increase is to be attributed to food intake.
