      A a = -3, b = -7 and c = -1 Correct Answer Incorrect Answer
      B a = -2, b = -7 and c = -4 Correct Answer Incorrect Answer
      C a = -2, b = 1 and c = -1 Correct Answer Incorrect Answer
      D a = -2, b = -6 and c = -1 Correct Answer Incorrect Answer

      Solution

      As the given matrices are equal, therefore, their corresponding elements must be equal. Comparing the corresponding elements, we get x + 3= 0, x= -3 z + 4 =6, z =2 2y – 7= 3y – 2 y = -5 a – 1= – 3, a= -2 0 =2c + 2, C= -1 b – 3 = 2b - 4, b=1   Simplifying, we get a = – 2, b = 1, c = – 1, x = – 3, y = –5, z = 2 so, value of a = -2, b = 1 and c = -1
