Answer:
This will result in a compilation error.
Here's the inheritance hierarchy:
Meg -> Lois -> Brian -> Stewie
Now Meg has 2 public Fxns, a() and toString().
Lois inherits from Meg and all its public functions as well but, overrides the a() fxn of its super class.
So finally Lois has fxns a(), b() and toString().
Brian extends Lois and inherits all the above listed fxns of Lois, but overrides the b() and toString() fxns.
Stewie extends Brian and inherits all the fxns of Brian, but overrides the a() and toString() fxns.
In the Main driver fxn, we call a() and b() methods of all these classes but, the base class Meg has no b() and it is not extending any class so its not available in its scope.
This results in a compilation error.

Answer:
The rank of disk capacities in decreasing order is:
1.petabyte,
2.terabyte
3.gigabyte
4.megabyte
5.kilobyte
Explanation:
Petabyte is largest among all and 1 petabyte equal to 1024 terabyte
Kilobyte is smallest among all and 1 kilobyte equal to 1024 byte
1 megabyte is equal to 1024 kilobyte
1 gigabyte is equal to 1024 megabyte
1 terabyte is equal to 1024 gigabyte
