why not a second option......both are same

Question:
If in a triangle XYZ, XY =  XZ and M, N are the mid points of XY and YZ, then which one of the following is correct?
Options:
A) MN = YZ
B) NY = NZ = MN
C) MX = MY = NY
D) MN = MX = MY
Solution:
Ans: (d) 


Since M and N are the mid points of XY and YZ respectively, therefore MN is parallel to XZ and \(MN=\cfrac{1}{2}XZ\)

\(MN=\cfrac{1}{2}XY\Rightarrow MN= MX= MY\)

OPTION "D" FOLLOWS FROM THE GIVEN CONDITION THAT XY=XZ BUT IT ISN'T GIVEN THAT XZ=YZ SO "B" DOESN'T FOLLOW
