Question

Your friend asks you to go to the museum on Saturday but you are not able to go. Which phrase would you use to decline the invitation?

¡Qué buena idea!

Me gustaría …

Lo siento...

¡Claro que sí!

Answer 1

Lo siento. Only because “what a good idea”, “I would like to”, and “of course” are not what you’d say to decline someone

Answer 2

Answer: Lo siento...

Explanation: All the other options are agreeing to the invitation, which is the opposite of what you’re tying to do — decline.
