the elements of both the matrix $A,B$ are the same. in matrix $B$ $R_1,R_3$ are interchanged.
as we know the important property of any determinants:
- if two rows (or 2 columns) of a determinant are interchanged the sign of the value of the determinant is changed.
here only one time rows is changed so the determinant should be multiply by $(-1)$.
$\therefore det (B)= -det(A)$
For Option A,
If $A, B$ are arbitrary $n × n$ matrices, then $det(AB) = det(A)* det(B)$
here $\Delta(A)=-160$, $\Delta(B)=-160 \rightarrow \Delta(AB)=-25600$
So Option $(A, C)$ is correct.
