C ?

IMO B
1) The number of odd numbers will depend upong whether x is even or odd.
ex: take x=3 and y=6
there are two even numbers and 1 odd number between 2 and 6
take x=2 and y=6
again there are 2 even numbers but there are now 2 odd numbers

NOT SUFF

2).As in the example above, the number of odd number changes when you change the total number of integers between x and y.

lets say if x is even
Y must be odd
number of odd integers wll be 12
if x is odd, y is even
number of odd numbers will be the same.
