Multiple choice issue in Pie chart

Hi everyone, I hope you are doing well, I am new in Power BI, and I have a challenge as below :

My scenario is I have a survey that asks people to select a popular item ( Multiable choose), So someone will choose A or B or A and B like below picture:

now the pie chart for the above table: 

but I need it to be only A or B or C. If someone selects A and B this will increase A and B ( not showing A, B).  Your support, please.
