Answer:
C)T
Explanation:
The period of a mass-spring system is:
As can be seen, the period of this simple harmonic motion, does not depend at all on the gravitational acceleration (g), neither the mass nor the spring constant depends on this value.
In the standing waves experiment, the string has a mass of 47.3 g and a length of 0.93 m. The string is connected to a mechanica

Let's call
and 
the masses of the two blocks. We can write Newton's second law for both blocks (sum of all forces acting on the block = ma). On block 1, we have two forces: the weight 
pointing downwards and the tension of the string T poiting upwards. On block 2, we have the tension of the string going right and the friction 
going left. Therefore
Summing the two equations, we find
and then using
we can find the acceleration:
Let's call
