Are you reading the question? It asks about an upstream system that has been configured to pass the date for a given batch of data to the Databricks Jobs API as a parameter. Upstream system usually don't use widgets. Widgets they are made for humans. Only C and D are correct but D is better so D.

dbutils.widget. Just passed the exam with score >80%. examtopics covers about 90% of questions. there were 5 questions I didn't see here in examtopics. But friends, you need to look at the discussions, and do test yourself. many answers provided here, even most voted answer, does NOT exists anymore in the exam - not the question, but the answer. Wish you all good luck, friends!
