Final answer:
In 'The Crucible', the character who is dynamic besides John Proctor is d) Elizabeth Proctor, as she undergoes significant emotional and personal growth throughout the play.
Step-by-step explanation:
The character in the play 'The Crucible' by Arthur Miller who is also dynamic besides John Proctor is Elizabeth Proctor. Dynamic characters are those who undergo significant internal change throughout the course of a story. While Abigail Williams may seem dynamic, her core motivations and behaviors largely remain the same throughout the story.
Rebecca Nurse remains steadfast in her beliefs and Mary Warren's changes are important but not as profound as those of Elizabeth Proctor. Elizabeth Proctor, like John, experiences a dramatic transformation in her understanding and emotions particularly about her relationship with John and her own mistakes, fitting the definition of a dynamic character.
