Hi canbtg,

Where did you find this question? I ask because it is terribly worded and the objective is not clearly defined.

As Rich said, this question is poorly worded.
Are we saying that the cows are identical, and the order of the horses doesn't matter?
Also, it sounds like all 8 horses must be next to each other.

If so, then I'd say the correct answer is A
Here are the arrangements

- HHHHHHHHCCCCC
- CHHHHHHHHCCCC
- CCHHHHHHHHCCC
- CCCHHHHHHHHCC
- CCCCHHHHHHHHC
- CCCCCHHHHHHHH

Of course, I may have incorrectly interpreted the question's intent.

Cheers,
Brent
