For any square matrix A of order 3, if k is a scalar, then |kA| (the determinant of kA ) can be expressed as |kA| = kn |A|
Where n is the order of the square matrix A, and |A| denotes the determinant of matrix A.
Explanation -
In this case, n = 3, so for any scalar k, |kA| = k3 |A|.
Hence Option(2) is correct.
