Pick the odd pair out.

Let's determine the logic connecting the first number (x) to the second number (y) in each pair:
Option B: 5−13

5×3−2=15−2=13
Option C: 9−25

9×3−2=27−2=25
Option D: 15−41

15×3−2=45−2=43

=41
Let's check alternative logic: 2x−something or 3x−2.
Let's check Option A with (x×3−2):

17×3−2=51−2=49
Since Options A, B, and C perfectly satisfy the pattern y=3x−2:

17×3−2=49

5×3−2=13

9×3−2=25

However, for Option D:

15×3−2=43

=41

Therefore, 15−41 is the odd pair.
