b. Jekyll transforming to Hyde
c. Hyde transforming into Jekyll
d. Utterson killing himself
Answer:
The correct answer is option c. Hyde transforming into Jekyll.
Explanation:
When he is desperate for the situation in which he became Hyde, Dr Jekyll asks for help from his great friend and colleague Dr Lanyon, to whom he sends a letter to meet and reveal his great secret.
Lanyon goes to Jekyll's house, but instead of finding him, he finds Hyde.
After a long talk, Hyde agrees to show Lanyon what was so troubling him, and made Lanyon swear that it was a professional secret and that he should help him.
When Hyde transforms into Jekyll, Lanyon couldn't believe it. It was something unethical and that went against all Lanyon's beliefs, so he decided to get away from his great friend, since he felt repulsion for the things Hyde had done.
Finally Lanyon falls ill and dies, after not enduring the events he saw that day at his friend's house.
Given this information we can say that the correct answer is option C.
