Step-by-step explanation:
The underlined domain words in the passage are related to the practice and preparation that actors undergo before presenting a play. The correct answer to the question is A. Acting. The process includes rehearsals, during which performers run lines to memorize them, avoid dropping lines or stepping on each other's lines, and learn blocking which is the choreography of where they need to stand and move on stage. This meticulous rehearsal and planning help ensure that the performance is smooth and that the actors can present their characters convincingly to the audience.
Technical and physical proficiencies are crucial for an actor, as is the memorization of both dialogue and blocking. Training and conditioning support the development of skills necessary for an actor to be fully present and in harmony with their role during a performance. Moreover, an actor must be able to project their voice and move their body in line with the character's needs and intentions, which often requires a foundation in voice and physical training.
