c. Reducing a matrix to echelon form is called forward phase of the row reduction process.

Step-by-step explanation:

Forward Phase in Row Reduction Process: It is the process in which operations are performed to get leading entries in non-zero rows.

Backward Phase: It is the process of reducing matrix from echelon form to reduced echelon form.
