#production-rules

A bank's rule-based system has three rules (OPS5-like; variables in angle brackets):

• N: (applicant ^name ⟨n⟩ ^salary < 35000 ^status NIL) → modify status to No
• LC1: (applicant ^name ⟨n⟩ ^salary > 100000 ^status NIL), (stocks ^holder ⟨n⟩ ^worth > 20000) → modify status to C1
• LC2: (applicant ^name ⟨n⟩ ^salary > 85000 ^status NIL), (stocks ^holder ⟨n⟩ ^worth > 50000), (credit ^user ⟨n⟩ ^score > 150) → modify status to C2

Working memory, by timestamp: 1 (applicant a, salary 5000, NIL); 2 (applicant b, salary 1035000, NIL); 3 (applicant c, salary 95000, NIL); 4 (credit b, score 100); 5 (credit c, score 155); 6 (stocks a, worth 10000); 7 (stocks c, worth 60000); 8 (stocks b, worth 25000). Which instantiations ⟨rule, WMEs⟩ are in the conflict set after the match phase? Select all that apply.
