MCQ
The matrix $\text{A}=\begin{bmatrix}0&0&4\\0&4&0\\4&0&0\end{bmatrix}$ is a:
  • ✓
    Square matrix.
  • B
    Diagonal matrix.
  • C
    Unit matrix.
  • D
    None of these.
✓

Answer

Correct option: A.
Square matrix.
Given: $\text{A}=\begin{bmatrix}0&0&4\\0&4&0\\4&0&0\end{bmatrix}$
Since, number of rows is equal to number of columns.
Therefore, $A$ is a square matrix.
Hence, the correct option is $(a).$
