We can't make any grouping so we need to minimize by taking individual ones

A'B'C+A'BC'+AB'C'+ABC=$A\bigoplus B\bigoplus C$

$A\bigoplus B\bigoplus C \\ \\ =(A\bigoplus B)\bigoplus C\\ =(A'B+AB')\bigoplus C\\ =(A'B+AB')'C+(A'B+AB')C'\\ =(A'B'+AB)C+(A'B+AB')C'\\ =A'B'C+ABC+A'BC'+AB'C'$

Therefore ans should be D

It's option (d)

It can be solved using two methods

1)  all variables are independent cannot be minimised further so the resul has to of 4 minterm expressions when you expand the options only option d would match

2) A'B'C+A'BC'+ABC+AB'C'


     A'(B XOR C)+A(B XNOR C)

     A XOR (B XOR C)

      A XOR B XOR C
