B) not possible at all because atom don't last that long 
C) very probable because of how incredibly small atoms are 
D) There's not really a way that scientists are able to make such an estimate.

Accepted Answer

A) The iron brick has twice the mass as well as twice the volume. 
B) The iron brick has twice the mass, but only half the volume. 
C) The iron brick has twice the mass, but its volume compared to the block of wood depends on the density of the wood. 
D) The iron brick has twice the mass, but its volume compared to the block of wood depends on the weight of the wood.
