C should be the answer.

If I name the various corners as follows

10 11 12
7 8 9
4 5 6
1 2 3

Then, the following are the possible routes (the shortest routes will be going horizontal and vertical only):

1-2-3-6-9-12
1-2-5-6-9-12
1-2-5-8-9-12
1-2-5-8-11-12
1-4-5-6-9-12
1-4-5-8-9-12
1-4-5-8-11-12
1-4-7-8-9-12
1-4-7-8-11-12
1-4-7-10-11-12

If there is any short cut to this, please let me know.

Answer is indeed 10.

To go from X to Y, you have to take 5 segments. 3 vertical segments and 2 horizontal segments in any order you want.

So this is just a matter of choosing (for instance) which of the 2 segments amongst the 5 will be horizontal segments.

Number is 2C5=\frac{5!}{3!*2!}=10
