The function $\mathrm{f}(x)=2 x-\left|x-x^2\right|$ is

Consider the statements given by following

(A) If $4+3=8$, then $5+3=9$

(B) If $6+4=10$, then moon is flat

(C) If both (A) and (B) are true, then $5+6=17$

Then which of the following statement is correct?

If $A=\left[\begin{array}{rrr}1 & -1 & 1 \\ 0 & 2 & -3 \\ 2 & 1 & 0\end{array}\right], B=\operatorname{adj} A$ and $C=5 A$, then $\frac{|\operatorname{adjB}|}{|\mathrm{C}|}=$
