Let (G,E,D) be a public-key encryption (PKE) scheme (without decryption error)

Let (G,E,D) be a public-key encryption (PKE) scheme (without decryption error) Show that perfectly secure PKE do not exist. For that, show that given "pk" and a ciphertext "c" computed as c = E(pk,m), it is possible for a computationally unbounded adversary to determine "m" with probability 1
