- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : For matrix A =\(\begin{bmatrix} 1 & 2 \\ 8 & 16 \end{bmatrix}\),rank of A = r(A) = 1
Reason R: For matrix A if |A| = 0, then it implies that rank of matrix A given by r(A) is less than full rank.
