Question

Which matrix is a zero matrix?

Options

• \[\begin{bmatrix}2&0\\0&2\end{bmatrix}\]

• \[\begin{bmatrix}0&1\\0&0\end{bmatrix}\]

• \[\begin{bmatrix}0&0\\0&0\end{bmatrix}\]

• \[\begin{bmatrix}1&0\\0&1\end{bmatrix}\]

Answer 1

Each of the four elements in the first matrix is \[0\]. Hence, it is a zero matrix of order \[2 \times 2\].
