Final answer:
The correct conjugation is 'Almuerzo'
Step-by-step explanation:
The correct conjugation in this sentence is 'Almuerzo'. The subject of the sentence is 'Yo' (I), so the correct verb form is 'Almuerzo'. Almuerzo is the first-person singular present tense conjugation of the verb 'almorzar' (to have lunch). This matches the subject 'Soy Rosita' (I am Rosita), which indicates that the speaker is referring to themselves.
