195. We have two metal spheres A and B with equal masses and the volume of sphere B is 4 times the volume of sphere A. We assign equal amounts of heat to them. If the specific heat capacity of A is half the linear expansion coefficient of B, and the linear expansion coefficient of A is half the linear expansion coefficient of B, what is the change in volume of sphere A compared to the change in volume of sphere B?
  • [(1)] $4$
  • [(2)] $2$
  • [(3)] $\dfrac{1}{2}$
  • [(4)] $\dfrac{1}{4}$
