The correct answer is: **a present perfect progressive verb** **Explanation:** In the sentence "The students have been organizing the school dance for the last month," the word **"organizing"** is part of the verb phrase **"have been organizing."** This verb phrase is in the **present perfect progressive tense**, which is used to describe an action that began in the past and is still continuing in the present. - **Present Perfect Verb:** Refers to actions completed at an unspecified time before now (e.g., "have organized"). - **Present Perfect Progressive Verb:** Emphasizes the continuous nature of an action that began in the past and continues into the present (e.g., "have been organizing"). - **Adjective:** A word that describes a noun (not applicable here). - **Conjugation:** Refers to the variation of a verb form to express tense, mood, etc. (not the specific role of "organizing" in this sentence). Therefore, **"organizing"** best fits the description of a **present perfect progressive verb** in this context.
