simple harmonic motion of a spring

Question

Suppose that the two springs and the two thingies are identical. Think about whether these two systems are significantly different in other respects and decide which one of the following statements is true

A: The systems have different periods because their motions are aligned differently with the gravitational field.

B: The hanging system has a slightly smaller period because the weight of the spring has to be accounted for.

C: The hanging system has a slightly larger period because the weight of the spring has to be accounted for.

D: The two systems have identical periods, no matter what the weight of the spring is
