If is a skew-symmetric matrix of order , then .
Assertion: If $A$ is a skew-symmetric matrix of order $3 \times 3$, then $\det(A) = 0$.
Reason: If $A$ is a square matrix, then $\det(A) = \det(A')$.
- (a)Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
- (b)Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
- (c)Assertion is true and Reason is false.
- (d)Assertion is false and Reason is true.
