What is the difference between the rule-based detection when compared to behavioral detection?

A.	Rule-Based detection is searching for patterns linked to specific types of attacks, while behavioral is identifying per signature.
B.	Rule-Based systems have established patterns that do not change with new data, while behavioral changes.
C.	Behavioral systems are predefined patterns from hundreds of users, while Rule-Based only flags potentially abnormal patterns using signatures.
D.	Behavioral systems find sequences that match a particular attack signature, while Rule-Based identifies potential attacks.
