Answer:
We must complete the conversation:
Señora Maurici: Buenas noches. Yo soy la señora Maurici.
Natasha: Mucho gusto.
Señora Maurici: ________.
And a rough translation of this is:
Señora Maurici: Good night. I am Ms. Maurici.
Natasha: It's a pleasure
Señora Maurici:______
and the options are:
Me llamo (my name is)
Buenos días (good day)
Yo estoy muy bien (I am fine)
Actually none of the options make a lot of coherence with the conversation, but the one that best suits it is "Yo estoy bien"
