Creating or marking an opportunity as lost will result in the change of a prospect's score

Creating or marking an opportunity as lost will result in the change of a prospect’s score. This is

because opportunities are one of the factors that affect the scoring of prospects in Marketing Cloud

Account Engagement. Scoring is a numerical value that indicates the level of interest or engagement

of a prospect in your products or services. Scoring is based on the actions and activities of prospects,

such as opening emails, clicking links, filling out forms, visiting landing pages, and creating or

updating opportunities. When an opportunity is created or marked as lost, the prospect’s score will

change accordingly. For example, if you have a scoring rule that adds 50 points to a prospect’s score

when an opportunity is created, and subtracts 25 points when an opportunity is lost, then creating or

marking an opportunity as lost will affect the prospect’s score by those amounts.

Answer B is incorrect because creating or marking an opportunity as lost will not result in no change

of a prospect’s score, as explained above. Reference: Scoring, Opportunities
