Answer:
The best answer is B
Explanation:
D is just admitting you are late when you aren't late yet, so we can eliminate that answer.
Many credit card companies may allow choice A. However, some will consider the first one as possibly fraudulent due to how relatively easy it is to backdate postmarks or get a postmaster to backdate them. Also, if A is true, then C must be true because checks are sent through mail which goes through the post office. We also must assume there is only one answer. B is the correct choice.
