Which answer corrects the error in capitalization?

In the month of February, Washington's birthday is an official federal holiday.

A.

Federal

B.

february

C.

Official

D.

Birthday

I think your answer would be B. February. Because it's the name of a month. We capitalize things like the names of our presidents, a famous place, or even a restaurant.

We can also capitalize the days of the month and days depending on the sentence.
