The answer is C. Subscription.
Software license is an agreement between the publisher of software and the individual user. The publisher is also known by the name licensor, while the purchaser is the name of the individual who purchased it.
To protect copyright infringement, a license program must be included with any software program you buy.
When purchasing software, it is important to consider the following features:
Software that is stand-alone does not come with bundles, or they can be installed on a single computer by one user.
The stand-alone program is more efficient than other programs. However, the downside is that it cannot be used in conjunction with any other software. It also comes with a hardware security key.
Subscription licenses can be used to rent the software on a subscription basis. Subscriptions can be on a monthly, quarterly, or annual basis.
Site license allows you to install software packages in multiple systems simultaneously.
It does not include a hardware security key.
Quick heal, for example, has a network license that can be used by 10 systems. Quick heal can be installed on 10 systems, and then it will block the license.
