Ok, another easy one, while people ponder my hard one

A large sheet of paper is 0.1mm thick. A man amuses himself by tearing it in half and putting both pieces together, and then tearing those into four sheets, and repeating the process until he has done it twenty-five times.

How high is the stack of paper now?

A) As thick as a book
B) As high as a man
C) As high as a house
D) As high as a mountain

 

 Are the aount of tears growing expodentially, for example 2,4,8,16,32 and so on?
