If the static temperature rise in the rotor and stator respectively are \[\Delta {{T}_{A}}\] and \[\Delta T,B\] then degree of reaction in an axial flow compressor is given by:

A) \[\frac{\Delta {{T}_{A}}}{\Delta {{T}_{B}}}\]              

B) \[\frac{\Delta {{T}_{A}}}{\Delta {{T}_{A}}+\Delta {{T}_{B}}}\]

C) \[\frac{\Delta {{T}_{B}}}{\Delta {{T}_{a}}+\Delta {{T}_{B}}}\]                      

D) \[\frac{\Delta {{T}_{B}}}{\Delta {{T}_{A}}}\]
