1. Object vs Class
Class is a template which holds state(fields), behaviour(methods) of objects.
An object is an instance of a class which has values for their states and corresponding behaviour.
Example:
Person is a class which holds name, age. class person { String name; int age; }
Person p1 = new Person("john", 21); Here p1 is an object whose name is john and age is 21.
2)
a,b) There are 25 leap years in both the cases.

In the first answer, 1900 is not an leap year. Because it is not divisible by 400.
Others are divisible by 4. Similarly 2000 is leap year because divisible by 4 but 2100 is not leap year as same reason as 1900.
