One end of a wire of length L and weight w is attached rigidly to a point in roof and a weight `w_(1)` is suspended from its lower end. If A is the area of cross-section of the wire then the stress in the wire at a height `(3L)/(4)` from its lower end is
A. `(w_(1))/(A)`
B. `(w_(1)+(w)/(4))/(A)`
C. `(w_(1)+(3w)/(4))/(A)`
D. `(w_(1)+w_(2))/(A)`
