The answer is A.

Explanation:

Regarding the information given in the question, we are asked to evaluate the options given which i believe have answers as follows;

B is true. Public-domain means that there are no individuals who hold a copyright over the subject which enables people to copy and distribute, the software in this case, freely.

C is true. Shareware is a term that is used for applications which have a certain trial period for users to decide whether the application meets their needs and demands and then they have to pay the required amount to keep using the software to its full potential. Most often it is the case that if the user does not agree to a payment, the features they are allowed to use are very limited and render the software almost useless until the payment is completed.
