Which word best describes the person shown in the image?
sociable
atrevida
inteligente
talentosa

I believe the answer is : Talentosa
Talentosa is a feminine form that is used to describe a person that possess a certain skill set. From the picture, we can see that the woman is capable of playing violin (which regarded as one of the most difficult musical instrument out there). Because of this, Talentosa seems to be the most suitable word to describe the person.
