When a body is subjected to biaxial stress i.e. direct stresses (σx) and (σy) in two mutually perpendicular planes accompanied by a simple shear stress (τxy), then maximum normal stress is

A. x + σy)/2 + (1/2) × √[(σx - σy)² + 4 τ²xy]

B. x + σy)/2 - (1/2) × √[(σx - σy)² + 4 τ²xy]

C. x - σy)/2 + (1/2) × √[(σx + σy)² + 4 τ²xy]

D. x - σy)/2 - (1/2) × √[(σx + σy)² + 4 τ²xy]

Please do not use chat terms. Example: avoid using "grt" instead of "great".
