How do you express gratitude and inquire about the participants' enjoyment in Spanish?

The correct response effectively communicates gratitude while also inquiring about the participants' enjoyment, using a phrase that is commonly understood and culturally appropriate in Spanish.

The expression "¡Gracias! Espero que lo hayan pasado bien." translates to "Thank you! I hope you had a good time," which directly conveys appreciation and simultaneously asks about the participants' experience. This dual focus on gratitude and engagement shows a thoughtful consideration for the attendees' feelings.

While other options may express gratitude or inquire about happiness, they lack the warmth and direct connection to the experience that the correct response provides. This makes option B the most suitable choice for conveying both appreciation and a specific inquiry about enjoyment.
