Which of these has special automatic update behavior?

This question is about different data types in MySQL and how they behave when you update data.
Let's break down each option:
* Option A: DATE - Stores a date (like '2023-12-18'). Updating a DATE value is simple; you just change the date. * Option B: TIME - Stores a time (like '10:30:00'). Similar to DATE, updating TIME involves changing the time value. * Option C: TIMESTAMP - Stores a timestamp (a combined date and time). This is the special one! Whenever you insert a new row or update a row in a table, MySQL automatically sets the TIMESTAMP column to the current date and time. You don't need to manually update it. * Option D: YEAR - Stores a year (like 2023). Updating a YEAR value is straightforward; you change the year.
So, the answer is Option C: TIMESTAMP.
This is because it has a special automatic update behavior, while the other options do not.
