Correct! The correct answer is b. "Cuánto tiempo hace que".

To arrive at this answer, you need to understand Spanish grammar and idiomatic expressions. The question asks "How long ago did you swim in the sea?". In this case, the correct response is "Hace dos meses" which means "Two months ago".

In Spanish, when talking about how long ago something happened, you should use the expression "Hace que" followed by the time period, like in this case "Hace dos meses que". This construction is used to indicate the duration of time that has passed since the action took place.

So, by understanding the grammar and interpreting the idiomatic expression correctly, you can determine that the correct answer is b. "Cuánto tiempo hace que".
