WebBecause B is NP-Complete, ∴, every A∈ NP is polynomially reducible to B. (as per property of NP-Complete). And B in turn is polynomially reducible to C (given). Because the property of polynomial is closed under the composition, We conclude that every A ∈ NP is polynomially reducible to C. Therefore C is NP-Complete. krchowdhary TOC 13/16 Web$\mathsf{NP}$ = Problems with Efficient Algorithms for Verifying Proofs/Certificates/Witnesses Sometimes we do not know any efficient way of finding the answer to a decision problem, however if someone tells us the answer and gives us a proof we can efficiently verify that the answer is correct by checking the proof to see if it is a …
