Answer 1

The correct option is (d) Modification of knowledge base

The best explanation: The modification of the knowledge base step is generally the final step in a single learning cycle. The knowledge base is modified in accordance with the outcome of the actions implemented by the reasoning engine. The existing information in the knowledge base is altered, or the action selection policy is changed. Otherwise, new knowledge entries are included in the database.
