UGC NET Questions (Paper – 1)

Statements A, B and C summarise the leap-year rule of the Gregorian calendar correctly. A states the basic rule for ordinary years divisible by 4 but not by 100. B adds the exception that years divisible by 400 are leap years even though they are century years. C notes that a century year divisible by 100 but not by 400 is not a leap year. E is also true because 366 days equal 52 weeks plus 2 days, giving two odd days. D is false since divisibility by 8 alone does not override the 100 and 400 year conditions, so A, B, C and E only are correct.

Option A:
Option A is incomplete because it omits E and thus does not connect leap years to the concept of odd days, which is often used in calendar-based reasoning questions. Without E, the relationship to day-of-week changes is not fully explained.

Option B:
Option B is also incomplete since it includes only B, C and E and omits A, failing to mention the basic divisibility-by-4 rule for non-century years. This makes the description of leap-year identification partial.

Option C:
Option C is correct because it collects all true statements, including the ordinary rule, the century-year modification and the odd-day implication, while rejecting D, which overgeneralises divisibility by 8. It reflects the treatment of leap years in NET calendar problems.

Option D:
Option D is incorrect as it introduces D, which asserts that every year divisible by 8 is leap, even though century exceptions contradict this, and it omits B. The combination therefore contains an error and cannot be considered correct.
