The correct options are
B February 29, 2020
C February 11, 2016
In a leap year, one day is added in February, which makes it 29 days in February.
We can also check whether the year is a leap year or not by dividing that particular year by 4. If it gives a whole number, then it is a leap year.
Dividing 2018 by four gives 504.5 and thus, it is not a leap year.
Whereas dividing 2016 by 4 gives 504 thus, it is a leap year.
