Solution

The correct option is C ΔL
Elongation in the wire is given by (ΔL)=FLAY
where F=Force applied
L=Length of wire
A=Area of cross-section
Y=Young's modulus of wire


F= Tension(T)
and T=W
Since, tension in both cases is same and all other parameters Y,A and L are also same.
So, elongation will be same in both cases.
