Answer:

B) noticing the thickness of the ventricle walls

Explanation:

Since the pressure in the right ventricle is higher than the atria, the muscle thickness is 5 to 10 mm. The muscle that has to bear the greatest pressure is the left ventricle and, therefore, the thickness of its wall is between 10 and 30 mm, since it must pump blood into the greater or systemic circulation.  For this reason it is possible to differentiate between the right and left part .
