D
if the data even in both Statements I and II together are not sufficient to answer the question

Solution:

Solution: $C . I = 100$

$\begin{array}{l} S u m = 1000 \\ R a t e o f interest = 10 % \\ 1 s t y e a r \Rightarrow 1000 + 100 = 1100 \\ 2 n d y e a r \Rightarrow 1100 + 110 = 1210 \\ 3 r d y e a r \Rightarrow 1210 + 121 = 1331 \end{array}$
