What is a common exhibit of a "persnickety" individual?

The term "persnickety" describes someone who is very particular and meticulous about details, often to the point of being fussy or hard to please. Therefore, the correct choice emphasizes a common behavior associated with such individuals—demonstrating attention to trivial details. This attention often manifests in their insistence on perfection and a focus on minor specifics that others may overlook or deem unimportant.

In contrast, overlooking details, pursuing simplicity, or maintaining an open-minded attitude would not align with the traits typically associated with a persnickety person. Those characteristics suggest a more relaxed or easy-going approach, which contradicts the notion of being excessively particular or fastidious.
