The ladder diagram shows three inputs, A, B, and C, which are ANDed together. The output of this AND gate is then ORed with the output of another AND gate which has inputs C, D, and E. Finally, the output of this second AND gate is ORed with the input E. This can be written as Y = (AB) + (ACD) + (DE) + (BCE). Therefore, the correct choice is B.
