The option or goods that do not have a marginal cost of zero is "Norton 360 disk" (option B)
The marginal cost in economics is the change in total cost that occurs when the amount produced is increased or the cost of producing more quantity.
The marginal cost is the incremental cost of producing an additional item. Assume that it costs $100 to produce 100 vehicle tires. It would cost $80 to create one extra tire. This is the marginal cost: the cost of producing one more unit of an item or service. The marginal cost is determined by the costs of production.
Hence, the reason why Norton 360 Disk will not have a marginal cost of Zero or the reason why Norton 360 Disk will have an additional cost with every unit produced is that there is hardware involved in the cost of it's production.
When software is produced and deployed on the cloud for download there is zero cost incurred for the production of the same software, all things being equal.
But if the company must produce an additional unit of Norton 360 disk, it must ensure the added cost of "disks" on which the software must be written prior to distribution.
