Question

1. choose the subject of the following sentences. me duelen las piernas. duelen las piernas yo

Explanation:

In the Spanish sentence "Me duelen las piernas", we analyze the subject. The verb "duelen" (hurt) agrees with the subject "las piernas" (the legs) in terms of number (plural). "duelen" is the verb, and "Yo" is not the subject here as the structure "me duelen..." is a reflexive - like construction for bodily pain where the subject of the verb is the part of the body (las piernas) that is performing the action of hurting (grammatically, the subject of the verb "duelen").

Answer:

B. las piernas (assuming the options are labeled as such, but based on the analysis, the correct subject is "las piernas")
