I am working on the Kmap for the Segment C on the 7 Segment Display.
The list of numbers that light up the 7 segment displays segment C are as follows:
The Kmap I came up with, without grouping yet, is as follows:
Then, when I start grouping, I came up with multiple variations. Some utilize the don't care conditions, and some don't. I'd like to know which one(s) are correct. It seems to me that they are all correct because I am following the grouping rules. If there isn't a single correct answer, then how do I know if the one I have is an acceptable answer?
Here is the list I came up with:
Finally, looking on the web, I encountered a site where they also have their version of the "solution". However, in one of their grouping, they have grouped 12 1s. One of the rules for grouping was that you can have only 2^n number of elements in a group. So, with that said, I don't know how their solution is correct. Here is the link that I am referring to:

Can somebody please clarify my confusions? Thanks!
