Einstein's Relativity seems to say that, if Mort and Velma are twins and Velma goes on a trip and then returns, Velma will then be younger than Mort and Mort will be younger than Velma. What is wrong with this reasoning?

A) Nothing is wrong with it.
B) The prediction about Velma's observation is not correct, because Velma is accelerated.
C) The effects of the theory of relativity cancel out due to Velma's acceleration, so that they are both really the same age when they get back together.
D) The prediction about Mort's observation is not correct, because Velma is accelerated.
E) What's wrong with this reasoning is that Albert Einstein was a fool and a hothead.
