Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R 

Assertion A : The system of equations x + y + z = 4, 2x - y + 2z = 5, x - 2y - z = 3 has unique solution. 

Reason R: If A is 3 x 3 matrix and B is a 3 x 1 non-zero column matrix. then the equation AX = B has unique solution if A is non-singular. 

In the light of the above statements, choose the most appropriate answer from the options given below:
