Which mode prevents MySQL to perform full checking of date parts?

Answer: Option B

This question is about how MySQL handles dates. Sometimes, you might enter a date that isn't completely valid, like "2023-02-30" (February only has 28 or 29 days).
MySQL has a setting that lets you decide how it should deal with these "invalid" dates.
The correct answer is Option B: ALLOW_INVALID_DATES.
Here's why:
* ALLOW_INVALID_DATES tells MySQL to accept these dates without any complaints. It will store the date as you entered it, even if it's technically incorrect.
* The other options (ALLOW_DATES_INVALID, PREVENT_DATE_CHECK, STOP_DATES_CHECK) are not actual settings in MySQL. Let me know if you have more questions!
