Which of the following could not be used to implement
a. return (lastname + ", " + firstname. substring(0, 1) + ".");
b. return (getlastname + ", " + getfirstname. substring(0, 1) + ".");
c. return (getlastname() + ", " + (0, 1) + ".");

b)

Explanation:

in section b) we can see that we don't have parenthesis at the end of every getter method call. for example we have a getter method for lastName as getLastName() but in return statement we don't call the getter method with parenthesis, that will cause compile time error.
