The most obvious thing that needs to be executed is letter B. This means that criteria-based sharing rules should still be used. Another thing that needs to run again is the previously fired workflow rules. These actions are usually done whenever there is a field update.
All of the rules that are associated with the object should be reevaluated otherwise, the program may not work the way that it should. It may not be ideal to answer E because active escalation rules can only run once. It is best to understand which rules can only run once in order to make the whole process work smoothly the next time that it is done.
if the record was updated with workflow field updates, fires before update triggers and after update triggers one more time (and only one more time), in addition to standard validations. Custom validation rules, duplicate rules, and escalation rules are not run again.
