Answer:
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.
D is true. "Copyright" is by definition is approved by the authorities and gives its creater the right to use, sell and change the creative product as they please. It works the same way for software products as well so the statement in option D is true.
A is wrong. Although they are freeware, this softwares still may have copyrights and even if they do not, they are very basic or even incomplete programs to satisfy the minimal needs of its users.
I hope this answer helps.

Answer:
public class Invitation
{
private String hostname;
private String address;
public Invitation(String n, String a)
{ // constructor that accepts two strings.
hostname = n;
address = a;
}
public String getHostname()
{
return hostname;
}
public void setAddress(String a)
{
address = a;
}
public String invite(String guest)
{
return "Hello" +guest+ ", you are invited to my party at " +address+". "+hostname+".";
}
public Invitation(String host, String address)
{
this.address = address;
this.hostname = host;
}
}
Explanation:
The Java program defines a class called "Invitation". The class constructor has two string arguments or parameters for the host of the event and the address. The invite method is used to generate the string invite message with the name of the guest as the argument. Use the "setAddress" method to set a new location of the event and the "getHostname" to get the name of the event host.
Answer:
b. 2.9!
Explanation:
There are is a mistake in the question.
Suppose the group consist of 10 kids and 2 adults, the number of ways in which they can form the line is:
= 2! 10!
= 2× 1× 10!
= 2.10!
But since that is not in the given option.
Let assume that the group consists of 9 kids and 2 adults, the number of ways in which they can form the line is:
No of ways the kids can be permutated = 9 ways
No of ways the adult can be permutated = two ways.
Thus; the number of ways in which they can form the line = 2! 9!
= 2 × 1× 9!
= 2.9!
