Final answer:
The character of Faustus undergoes a significant transformation throughout the play, becoming increasingly ambitious and morally compromised.
Step-by-step explanation:
The character of Faustus undergoes a significant transformation throughout the play.
At the beginning of the play, Faustus is portrayed as a highly ambitious character who craves knowledge, power, and worldly pleasures. He is willing to make a pact with the devil in exchange for these desires.
However, as the play progresses, Faustus becomes increasingly morally compromised and loses sight of his initial goals. He becomes obsessed with indulging in sensual pleasures and loses interest in knowledge and power.
Therefore, the correct answer is option C: Faustus becomes increasingly ambitious and morally compromised.
