A
Present participle
💡 Explanation:
In Perfect Continuous Tense, the structure is auxiliary verbs (have/has/had + been) + main verb in -ing form. This -ing form is called the Present Participle. For example: "has been working" (Present Perfect Continuous) or "had been sleeping" (Past Perfect Continuous). Past Participle is used in Perfect tenses (without continuous) like "has worked".
