What does "Si tomaron fotos, no duden en etiquetarnos en Instagram." encourage participants to do?

The statement "Si tomaron fotos, no duden en etiquetarnos en Instagram" directly encourages participants to tag the organization if they have taken photos. The use of the phrase "no duden en etiquetarnos" translates to "do not hesitate to tag us," which clearly communicates the desire for participants to mention or tag the organization in their Instagram posts. This not only serves to promote engagement on social media but also helps the organization to connect with the participants' experiences visually.

The other options don’t align with the instruction given. For instance, sharing favorite pictures or printing photos does not involve tagging the organization directly, and sending photos through email is not mentioned in the statement. The encouragement is specifically focused on tagging in the context of social media.
