The uploaded study guide identifies C. Account Object as the correct answer.
The scenario requires Salesforce to represent existing individual customers in a way that allows financial advisors to open a customer record and see associated business opportunities. The study guide therefore selects the Account object rather than Case or Lead.
A Case represents a support or service issue rather than the customer entity itself, so it would not provide the correct foundation for representing the person whose opportunities need to be viewed. A Lead represents a prospective individual or organization before that prospect is converted into the established Salesforce customer structure. The scenario, however, refers to customers whose business opportunities must already be associated with their records.
The fact that the bank currently serves individuals rather than corporate customers does not change the study guide's selected Salesforce object. The essential UX and data-model requirement is to represent the customer using the object intended to anchor the relationship and associated opportunities.
Correct object selection directly affects the quality of the user experience because advisors need a coherent customer record from which related sales activity can be viewed.
