Consider two distributions $P_0,P_1$ with the same supports and a distinguisher $\mathcal{A}$ that makes $q$ queries. Tick the \textit{incorrect} assertion.
A. When $q=1$, $\mathsf{Adv}(\mathcal{A})\leq d(P_0,P_1)$ where $d$ is the statistical distance.
B. When $q>1$, $\mathsf{Adv}(\mathcal{A})\leq \frac{d(P_0,P_1)}{q}$ where $d$ is the statistical distance.
C. When $q=1$, the strategy ``return 1 $\Leftrightarrow \frac{P_0(x)}{P_1(x)}\leq 1$'' achieves the best advantage.
D. To achieve good advantage, we need to have $q\approx 1/C(P_0,P_1)$ where $C$ is the Chernoff information.
