One end of a 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 [IIT 1992]

• A.             \[\frac{{{W}_{1}}}{S}\]      
• B.             \[\frac{{{W}_{1}}+(W/4)}{S}\]
• C.             \[\frac{{{W}_{1}}+(3W/4)}{S}\]
• D.               \[\frac{{{W}_{1}}+W}{S}\]
