Answer:
C. They all crave companionship.
Explanation:
According to the book Of Mice and Men
by John Steinbeck, Lennie, Curley, Candy and Whit are all social outcasts who do not participate in social events that other men of their age would engage in. They are described as being crippled in a way, either physically or mentally.
Therefore, they all crave companionship.
