Suppose that you possess a $D$-ary encoding $\Gamma$ for the source $S$ that does not satisfy Kraft's Inequality. Specifically, in this problem, we assume that our encoding satisfies $\sum_{i=1}^n D^{-l_i} = k+1 $ with $k>0$. What can you infer on the average code-word length $L(S,\Gamma)$?
A. $L(S,\Gamma) \geq H_D(S)-\log_D(e^k)$.
B. $L(S,\Gamma) \geq k H_D(S)$.
C. $L(S,\Gamma) \geq rac{H_D(S)}{k}$.
D. The code would not be uniquely-decodable and thus we can't infer anything on its expected length.
