a) The final temperature of both substances is closer to the initial temperature of substance A than the initial temperature of substance B.

b) The final temperature of both substances is closer to the initial temperature of substance B than the initial temperature of substance A.

c) The final temperature of both substances is exactly midway between the initial temperatures of substance A and substance B.

d) The final temperature of substance B is greater than the final temperature of substance A.
