In applying one or more row operations while finding `A^(-1)` by elementary row operation we obtain all zeroes in one or more, then `A^(-1)`.

Explanation

To solve the problem, we need to analyze what it means when applying row operations to find the inverse of a matrix \( A \) results in one or more rows (or columns) of all zeros.

### Step-by-Step Solution:

1. **Understanding the Matrix Inverse**:
The inverse of a matrix \( A \), denoted as \( A^{-1} \), exists if and only if the determinant of \( A \) is non-zero. This is a fundamental property of matrices.

**Hint**: Remember that the determinant gives us information about the invertibility of a matrix.
