Answer:
They enjoyed their time together is the correct answer.
Step-by-step explanation:
Mr. Utterson and Mr. Enfield are both characters of Strange Case of Dr Jekyll and Mr Hyde by R. L. Stevenson. The novel narrates the story of Dr Jekyll and his strange relationship with Mr Hyde.
The excerpt mentions that in spite of their own personalities (none of them really talked to the other one and they did not look like friends when they were together) they had a bond and, apparently, enjoyed time together.
