Final answer:
The lawyer who revised Dr. Jekyll's will to leave everything to Mr. Hyde is Mr. Utterson.
Step-by-step explanation:
The lawyer who revised Dr. Jekyll's will at his request, in order to leave everything to Mr. Hyde is: A. Mr. Utterson. This question relates to the novel 'Strange Case of Dr Jekyll and Mr Hyde' by Robert Louis Stevenson. In the story, Mr. Utterson is a close friend of Dr. Jekyll.
He is also the lawyer responsible for Dr. Jekyll's legal matters, including the revision of his will that becomes a central plot device in the story. Mr. Utterson's role includes addressing the implications of this will, which leave his friend's entire estate to the mysterious Mr. Hyde.
This chapter shows Utterson's intensely loyal and caring personality, especially towards his friend Jekyll. The strong bond between Jekyll and Utterson is emphasised. It also shows how seriously he takes his profession, and how he lets it define him. Mr. Utterson the lawyer was a man of a rugged countenance that was never lighted by a smile; cold, scanty and embarrassed in discourse; backward in sentiment; lean, long, dusty, dreary and yet somehow lovable.
