To answer this question, we need to understand that all months have at least 28 days. However, the key here is to recognize that there is one specific month that always has exactly 28 days.
Let's go through each option to understand why it is correct or incorrect:
Option A) 1 - This option is incorrect because more than one month has 28 days.
Option B) 7 - This option is incorrect because more than seven months have 28 days.
Option C) 12 - This option is correct. All twelve months have at least 28 days.
Option D) None of the above - This option is incorrect because it does not acknowledge that all months have at least 28 days, and specifically, one month has exactly 28 days.
The correct answer is C) 12. This option is correct because all twelve months have at least 28 days.
