A,B,C,D,E are the rules in a task T 1. B over rides A, C over rides B and E over rides D. in a specific instance, the conditions of A,C,D are true and the conditions for B,E are false. Which rules will fire finally?

In this override scenario, we must evaluate which rules' conditions are true AND which are not overridden. Rule A is true and not overridden (B is false, so B cannot override A). Rule C is true and not overridden (B is false, so B's override of C doesn't take effect). Rule D is true and not overridden (E is false, so E cannot override D). Therefore A, C, and D will fire.
