Answer:
Option d is the correct answer for the above question.
Explanation:
- Authentication is a process that enables the user to enter the system. This process helps to secure the data. It is because with the help of this only valid users can enter the system. In this process, the system asks some unique information from the user which can only be known to the valid user.
- Some systems put two types of authentications one is some information about the valid user and the other is a fingerprint scan that takes the data of the user finger and matches with their user name and password. If it matches then only he can enter into the system.
- The above question asks about the mechanism which is used for multifactor authentication. This authentication is known as a fingerprint scan. So the option D is the correct answer while the other is not because:-
- Option 'a' states about the username which is used in the first authentication.
- Option b states about pin which can be used in the place of username.
- Option c states about the security question which is used when the user forgets the password.

Explanation:
We have a set of wildcard characters. And they are the? and *. We use * for multiple characters, and ? for the single character. / is used for an escape sequence. like if we want to use it? as a symbol and not as wildcard characters, then we will make use of the /. And suppose we want to find all the words that are of type ?ard like the card and hard, then we will make use of ? which means that place can be replaced by one character.

Without more information for what the programming language is I cannot give a full answer, so I listed a potential method for calculating salary.
To calculate the salary (Java):
public static double getSalary(double salary) {
if (salary < 40000) {
return salary + (salary * 0.05);
}
return 2000 + ((0.02 * salary) + salary);
}
To calculate the salary (VB .Net):
Function getSalary(ByVal salary As Double) As Double
If salary < 40000 Then
salary = salary + (salary * 0.05)
Else
salary = 2000 + ((0.02 * salary) + salary)
End If
Return salary
End Function
Answer: When we type the value into two different cells and then have another cell with the answer, we can then easily change the values in the cells and Excel will automatically recalculate the solution for us.
Hope this helps. :)
