Given the logic functionF(A,B,C,D)=m(0,2,5,6,7,8,9,12,13,15)

a) find two different minimum AND-OR circuits which implement F. Identify two hazardsin each circuit. Then find an AND-OR circuit for F that has no hazards.

b) the minimum OR-AND circuit for F has one hazard. Identify it, and then find an OR-AND circuit for F that has no hazards.
