Using Karnaugh map to change the logic function y = C + ABC into the simplest and or expression

Why use Kano if you can use Boolean? Y = C + ABC, y = C (1 + AB), y = C, OK!

10. On the reduction of irrelevance in Karnaugh Map Karnaugh map is shown in the figure. If the grid corresponding to the minimum terms M13, M15 and M11 is regarded as 1 according to the independent terms, the maximum bounding circle can be obtained, and L = D can be obtained. If the independent terms are not used, the maximum bounding circle can be obtained The answer is not the same at all. May I ask what kind of simplification method is right?
