A circular shaft is subjected to the combined action of bending, twisting and direct axial loading. The maximum bending stress \[\sigma \]maximum shearing stress \[\sqrt{3\sigma }\] and a uniform axial stress \[\sigma \](compressive) are produced. The \[\sigma \]maximum compressive normal stress produced in the shaft will be

A) \[3\,\sigma \]                             

B) \[2\,\sigma \]

C) \[\sigma \]                                 

D) Zero
