Answer:
Option one
Step-by-step explanation:
Helping verbs "help" the main verb of a sentence to express the main verb's tense, mood, or voice.
Let's break down the sentence and highlight the verbs:
You could have been cleaning your room all night!
Could is a helping verb.
Have is a helping verb.
Been is a helping verb.
Cleaning is an action verb.
Therefore, the linguistic formula is:
Helping verb + helping verb + helping verb + action verb.
