Answer:
C, B, D, A
Explanation:
"Andar con pies de polmo" means that you or the person is very cautious.
"No hay color" means that there is no comparison.
"Dormir con pierna suelta" means to sleep like a log.
"Dar la vuelta a la tortilla" means that basically "the flip switched"
The answer is A. Tú tocas el piano. Because Tu tocas is the only correct way of saying you are playing the piano in this instance. C is saying "tocan" which is wrong because it's saying you but then using a the group form of playing. The same thing with B, it's also using the group form of playing and it's past tense. And D is using the I form of playing not the you form.
