Answer : Large number of small particles—individual atoms or molecules.</span>
The answer is A. Plasmodesmata. It's a narrow pathway between cells.
Explanation:
As it is known that
molecule is a non-linear molecule. Therefore, its isochoric heat capacity will be as follows.

= 
= 18 R
Also, 
where,
= molar heat capacity
M = molecular mass
= specific heat
Hence, calculate the value of
as follows.



This means that value of isochoric specific heat is
.
Yes, we have to assume ideal gas behavior because for ideal gas:
dU = 
Whereas for real gases "
" has to be added here.
It does not affect the mass, it only affects the outwards appearance of the ice/water.
