If name is a String instance variable, average is a double instance variable, and numOfStudents is a static int variable, why won’t the following code from a class compile?public Student(String s) {name = s;average = getAverage(name);numOfStudents++;}p ublic double getAverage(String x) {numOfStudents++;double ave = StudentDB. getAverage(x);return ave;}public static void setAverage(double g) {average = g;}a. The setAverage() method can’t access the average instance variable. b.The getAverage() method can’t increment the numOfStudents variable. c.The constructor can’t increment the numOfStudents variable. d.The getAverage() method can’t call a static method in the StudentDB class.

a.

Explanation:

Based solely on the snippet of code provided on the question the main reason why the code won't compile (from the options provided) is that the setAverage() method can’t access the average instance variable. Since the average variable is an instance variable it means that it only exists inside the one of the functions and not to the entire class. Meaning that in this scenario it can only be accessed by the Student function and once that function finishes it no longer exists. Also, it is not one of the options but if these variables are instance variables as mentioned their type needs to be defined inside the function.
