The exercise aims for you to practice proper conjugation with the correct personal pronoun.
Here is the translation of the sentence:
We talk to the lady
Here is the indicative conjugation of the verb hablar in present:
Presente
yo hablo
tú hablas
él/ella/Ud. habla
nosotros hablamos
vosotros habláis
ellos/ellas/Uds. hablan
As you can see the correct conjugation would be hablamos because the subject is nosotros. The other options are conjugated hablo for yo, hablas for tú and habláis for vosotros.
