Answer:
Los hondureños están vendiendo sus artesanías en la fortaleza en Omoa.
Step-by-step explanation:
The only possible answer is vendiendo, which in English means "selling". The translation would be "The Hondurans are selling their handicrafts in the Omoa fort". Visitando means "visiting", which doesn't make sense. Neither does "leyendo", because it means "reading". Finally, "podiendo" is not a word in Spanish, it doesn't exist. Note that in Spanish nationalities aren't written in capital letters as in English: hondureños / Hondurans.
