For any two matrices A and B of suitable orders, (AB)' is equal to:

For any two matrices A and B of suitable orders, (AB)' is equal to:

• A. A'B'
• B. B'A'
• C. AB
• D. BA

Answer: B) B'A'

Explanation: By the reversal law of transposes for matrix multiplication, the transpose of a product is the product of the transposes in reverse order: (AB)' = B'A'.
