please show all the steps.......

Given the KMAP, write the equation for the COMPLEMENT function as POS. (A' + B' + C')(A' + B + C)(A' + B' + D)(A + B + C' + D')(A + B' + C + D') (A + B + C') (A + B + D) (A + B' + C) (A' + B' + C' + D') (A' + B + C + D') (A' + B + D) (A' + B + C') (A' + B' + C) (A + B' + C' + D') (A + B + C + D') (A + B + C) (A + B + D) (A + B' + C') (A' + B + C' + D') (A' + B' + C + D') none of the choices
