Can we say that a zero matrix is invertible?

Explanation of the right response:
Invertible Matrix:
Any square matrix $A$ of order n × n is called invertible matrix if there exists another $n\times n$ square matrix $B$
such that, $AB=BA=I$,
where $I$ is an identity matrix of order $n\times n$.
Hence, an invertible matrix cannot contain a zero matrix.
