Final answer:
The appropriate verb to fill in the blank is "estás" (OA).
Step-by-step explanation:
The appropriate verb to fill in the blank in the sentence is estás (OA). The correct sentence would be "Ignacio, estás enojado conmigo." This is because the verb "estar" (to be) is used to express temporary states or conditions, such as being angry. In this case, "estás" is the second person singular form of the verb "estar" in the present tense, which matches the subject "Ignacio."
