The correct answer is D. all of the mentioned.
A Personal Consultant knowledge base contains information in the form of parameters, contexts, and production rules.
Parameters are variables that can be used to represent different values. For example, a parameter might represent the name of a person, the date of a meeting, or the amount of money in a bank account.
Contexts are sets of parameters that are used to define the scope of a rule. For example, a context might define the set of people who are allowed to access a particular piece of information.
Production rules are statements that describe how to
make inferences from the information in the knowledge base. For example, a production rule might state that if a person is a customer, then they are allowed to purchase products from the company.Parameters, contexts, and production rules are all essential components of a Personal Consultant knowledge base. They allow the knowledge base to represent information in a way that is both flexible and efficient.
