How can the threshold for the confidence level be set for the intent of a dialog node in the IBM Watson Assistant service?

A. The confidence level cannot be set within the Dialog and should be done programmatically within the application code.

B. On the drop-down of the Dialog node, the condition for confidence levels can be set for the intents defined in your Dialog node.

C. The confidence level threshold is already set for each Dialog node at "0.2". It can be overridden by turning off the confidence level on the improve tab within the Watson Assistant workspace.

D. It can be a condition within the Dialog node alongside the intent. For Example, intents [0].confidence<0.8
