14. Which month has exactly 30 days?
Answer: B
November has exactly 30 days.
November is one of the months that has exactly 30 days, making it the correct answer to the question.
A) March
March has 31 days, which makes it incorrect. It does not fit the criteria of having exactly 30 days.
B) November
November is indeed a month that contains exactly 30 days, fulfilling the requirement specified in the question.
C) February
February typically has 28 days, and 29 days in a leap year. In either case, it does not have 30 days, so it is incorrect.
D) July
July has 31 days, making it an incorrect option as it does not meet the condition of having exactly 30 days.
E) October
October also has 31 days, which disqualifies it from being the correct answer to the question regarding months with exactly 30 days.
Conclusion
November is definitively the correct answer as it is the only month listed that contains exactly 30 days. All other options are incorrect because they either have more or fewer than 30 days, thereby failing to meet the question's criteria.
