If A is a matrix of order 3, and |adj A| = 36, then which of the following statements is true for |A|?

|A| can be 6. |A| can be -6. |A| can be both 6 and -6. |A| can never be negative.

|A| can be both 6 and -6.

|adj A| = \( { |A| }^{ n-1 } \), where n is the order of the matrix |adj A| = \( { |A| }^{ 3-1 } \) 36 = \( { |A| }^{ 2 } \) |A| =6 or -6
