Final answer:
The correct verb form to complete the second sentence is B. dolió.
Step-by-step explanation:
The correct verb form to complete the second sentence is B. dolió.
In the first sentence, the speaker describes a past event using the reflexive verb lastimarse (to hurt oneself). In the second sentence, the speaker wants to express that the legs and the back hurt for a week. Since the subject is still the speaker (me), the correct verb form is the third-person singular form dolió.
Example: El mes pasado, me caí de las escaleras y me dolió las piernas y la espalda por una semana.
