how can I do these and can you explain the step by step process?

QUESTION 1 What is the minimum sum-of-products function for f(a,b,c) = m(3,4,6,7) O fab.c) = labc + alblc + abc + abc O fab.c) - abc ablc + labc + albic + albc + ablc + abc None of these Of(a,b,c) = lac + alc + bc f(a,b,c) = lalbc + labc + alle + ab!c + abc flab.ca.bC Of(a,b,c) = lac + alc + ab f(a,b,c) - bc + alc QUESTION 2 What is the canonical sum-of-products function for f(a,b,c) = m(3,4,6,7) Of(a,b,c) = !abc + alblc + abc + abc = Of(a,b,c) = bc + alc of(a,b,c) = lalbc + labc + albic + ab!c + abc O fab.c) = lac + alc+bc f(a,b,c) = lac + alc + ab O Rabcabclable + labc + alb c + albc + ablc + abc O fab.ca.b+c None of these QUESTION 3 For the logical circuit f(a,b,c) = lac + alc+ ab, the number of inputs is the number of gtes is so the costis
