AnswerClick to flip back
A
When used if no value present
B
When used if property is missing
C
Whenever used
💡 Explanation:
The options "Whenever used", "When used if no value present", and "When used if property is missing" all represent backward chaining strategies where calculation is triggered by property retrieval. Conversely, "Whenever inputs change" is a forward chaining strategy where calculations are pushed automatically as soon as source values update.
