Answer:
Royalty payment
Step-by-step explanation:
Adam and his team owns the software and has also acquired a license for it which makes it their sole property, in order for any organization to use the software for business to strengthen their security they would have to pay in the form of Royalty payment because Adam and his team will hope to grant access to other companies to the same software. so giving it to each of the companies would mean granting access to them and the only way they can do it is to collect payments in form of Royalty and not outright sale.
A royalty payment is a payment made by an organization to another for the usage of an asset owned by that company receiving the payment ( Adam's software development company ).
