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