Solution

The correct option is D remains same
Breaking force $=$ Breaking stress $\times$ Area of cross-section. When the wire is cut to half, there is no change in the area of cross-section of the wire. Therefore, there is no change in the maximum load (i.e., breaking force) the wire can support.
