Answer
Consider the data's role and association. Frame the concept in practical terms so you can explain it during interview discussion.
Data belongs to the class it logically associates with. 'Product' should contain specific product details. 'CartItem' should have product-related details specific to the cart context, like quantity. 'Customer' should hold personal details. For example, 'Product' has 'price', 'CartItem' may have 'quantity', and 'Customer' has 'name'.
