A, B and C are matrices: A ( B + C ) = AB + CA
- A.
  
  Always true
- B.
  
  Sometimes true
- C.
  
  False
Correct Answer
B. Sometimes true

Explanation
The given equation states that the product of matrix A with the sum of matrices B and C is equal to the sum of the products of matrix A with B and matrix A with C. This equation is sometimes true because matrix multiplication is not commutative, meaning the order of multiplication matters. In some cases, the equation will hold true, but in others, it will not. Therefore, the statement "Sometimes true" is the correct answer.
