What should i hep/answer ? :)
As a spanish speaker, I believe it is
a. Es buena idea que hagas una reservación.
Answer b is the right choice
Hey there!
It would be:
El dia de la independencia.
Hopefully this helps!
(Translates to the say of the independence, or independence day).
Hey man/girl, I would love to help you, but I cant when we cant hear what its saying, so therefore we cant help you unless you somehow post a recording of how it sounds so we can tell you the answer, I'd be happy to help, just post a recording or send a message of the recording so I can tell you the answer
