Official Solution:

We’ll go for LOGICAL because that is our first choice in Data Sufficiency.

In order to calculate the total value of both the investments at the end of the year, we need to know the value of each of the investments. For each investment, there’s one element missing: the rate by which the investment grew for one, and the invested amount for the other. We need both these missing parts to get the total value. Neither statement alone provides that, but both statements together do. (C) is correct.
