Final answer:
The correct word to fill in the blank is 'llamo'.
Step-by-step explanation:
The correct word to fill in the blank is llamo. The phrase in the question is asking for the name of the person, Mauricio, which is equivalent to saying 'I am called Mauricio' in English. The Spanish verb 'llamar' means 'to call' or 'to be called', so the correct conjugation of this verb in the first person is 'llamo'.
