I have the Karnaugh Map below and I need to implement it using a Multiplexer which has a1 as the select line, hence I would need a 2x1 Multiplexer if I'm not wrong.
My problem is that I don't know how to group the ones together to find the implicants in this case, I tried as you can see from the picture I uploaded but I don't know if it is any correct.
I would appreciate it if someone could help me figure this out, thank you in advance.

If A1 is the select control, then instead of one logic function of 4 variables A0,A1,B0,B1 to implement there will be two logic functions of 3 variables A0,B0,B1 to implement. So minimize the blue & yellow K-maps separately, then select between them.
