Which of the following statements are relevant to the process of querying a Horn clause knowledge base (KB)? Select one or more: O a. To prove that KB = a is equivalent to showing that KB* ^ ¬a has no models. O b. To demonstrate that (KB* ^ ¬a) has no models is really showing that (KB* → a), where KB* is the conjunction of all the sentences in the KB. O c. The expressions (KB* → a) and KB = a are connected via the Deduction Theorem. O d. None of the above statements are relevant to the process of querying a Horn clause KB.
