The pressure ratio obtained from a centrifugal compressor is lower than that which can be obtained from the axial flow compressor. I think the key to this question is the use of the word stage. If you consider 1 stage of an axial compressor (rotor + stator) its pressure rise is not that great. A number of stages are required to give high pressure ratios.

A stage of a centrifugal compressor is its impeller and diffuser. This will give a higher ratio than a single axial stage. The ratio produced is dependent on speed of the impeller and its diameter.

Questions are normally asked to compare the centrifugal and axial compressors. I do not like the wording of this question and can understand your confusion.
