An organization has two lines of business: selling books for children and reselling college textbooks.
The division selling books for children can use the same basic user interface (UI) as the division reselling textbooks with the exception of the payment methods.

in this scenario?

Answer options

• A. Place the UI rules in the base layer, and create a new layer for the payment rules for both lines of business.
• B. Place the UI rules and generic payment method rules in the base layer, and create a new layer for the division-specific payment rules.
• C. Place the UI rules in the base layer, and create a parallel base layer for the payments rules.
• D. Place the UI rules in the base layer, and create a new layer for the payment rule for each division.

Correct answer: B

Explanation

The correct answer is B because it allows for a common base layer containing the shared UI and generic payment methods while providing a separate layer for division-specific payment rules. Option A incorrectly suggests a single layer for payment rules for both divisions, which doesn't allow for customization. Option C incorrectly suggests a parallel base layer for payments, which is unnecessary. Option D implies separate layers for each division's payment rules but fails to account for shared payment methods in the base layer.
