Answer:
A.
Step-by-step explanation:
The symbol that applies to both St. John and Jane in chapters 31 and 32 is dreams.
In both chapters, we can see that both Jane and St. John have dreams. Jane's dreams of Rochester describe her emotions and spirituality. Though she is enjoying her new life, yet she is caught in her feelings for Rochester.
In the case of St. John, his dream of going to India as a missionary is seen in chapters 31 and 32.
Therefore, option A is correct.
