Right OPTION is (C) SET of all possible choices

For explanation I would say: A decision tree is a DIRECTED graph with a HIERARCHICAL set of nodes and arcs. A node represents a choice or a decision. An arc from one decision node to another decision node represents all possible choices associated with that node.
