The correct answer is B. A choral ode
Step-by-step explanation:
In theater and plays, a stasimon refers to a song or choral ode that is sang by the chorus along with the orchestra between different actions or episodes that took place in a play. In general terms, the stasimon was broadly used in Ancient Greece theater, especially in Greek tragedy and was composed by strophes and antistrophes that were the response to the strophes. Additionally, stasimon did not usually follow the same meter than regular odes. Therefore, a stasimon can be defined as a choral ode.
