Question

Which of the following tells what you have just done? Estoy bailando. Hace tres días que bailo. Hace tres días que bailé. Acabo de bailar.

Answer 1

Answer:

Acabo de bailar

Explanation:

To tell someone what you just have done, you should use ‘acabo de bailar’. The word ‘acabo’ in this sentence means ‘I just danced’. The other sentences are in different tenses.

‘Estoy bailando’ is in the present form, it means you are dancing now. ‘Hace tres días que bailo’ means you are still dancing now and you started three days ago. And ‘Hace tres días que bailé’ means you danced three days ago.

Answer 2

Estoy bailando means I am dancing
Hace tres días que bailo means I danced three days ago
Hace tres días que bailé means It's been three days since i danced 
Acobo de bailar means I have just danced
so the answer is 
Acobo de bailar
