Explanation:

The dictionary defines "gibe" as a verb meaning to make taunting/jeering remarks. We need to identify the sentence where "gibe" functions as this verb. The first, second, and fourth sentences use "gibe" as a noun (referring to the remark itself), while the third uses it as a verb describing the critics' action of jeering.
