Answer:
d
Step-by-step explanation:
personally idk anything about ballet, but d is the one that would make more sense.
1. the dance practices his dance. well no cause he just performed.
2.the dancer practices many hours. why? if he already performed.
3. the dance memorizes the positions of the dance. yes but why if he only needs the ending and "pasiciones" is the one where the are on the bar and do position 1 and then 2.
and three makes the most sense, it's one move and it's common ending dances like that. from what I have seen
