Answer:
shareware
Step-by-step explanation:
It is the shareware, which is available for free for a certain period, and after that, the actual fee is charged for continued usage. The public domain is free from copyright, patent or trademark laws, and is the public property. The open-source is the free code of software that is available with code for the whole developer community. And it is shared among all the developers. And the developer can be anybody. The freeware is the software that is provided free of cost by the publisher. And there is no set of rights, licenses or EULA that governs its distribution, and each publisher frames his own set of rules for the usage of the freeware.
