Which of the following matrices is not a square-matrix?

Options

  1. A[1]
  2. B[ array ll 2 & 2 2 & 2 array ]
  3. C[ array lll 3 & 3 & 3 array ]
  4. D[ array lll 1 & 1 & 1 1 & 1 & 1 1 & 1 & 1 array ]

Correct answer

C. [ array lll 3 & 3 & 3 array ]

Step-by-step solution

Obviously (c) is not a square matrix. Its order is 1 3 .
