Given a knowledge base (KB) that consists of two components, A and B, one can check if a statement C is a logical consequence of KB by formulating the compound statement "If (A and B) then C." Using this approach, determine in which of the following cases C is a logical consequence of the given KB. A KB=(p⇒q. q^-p}, C= {p} B KB=(pq, p), C= (p^q} KB=(pq, q), C={p^q} KB=(p⇒q, q⇒r), C= {p⇒r}
