Solution (By Examveda Team)

This question is asking about how to get the most recent sequence number generated in a MySQL database. Let's break it down:
Sequence Number: This refers to a unique number that's automatically assigned to each new entry in a table. Think of it like a running counter.
MySQL: This is the specific database system we're working with.
Now, let's look at the options:
Option A: LAST_INSERT_ID() This is the correct answer. It's a built-in function in MySQL that gives you the last sequence number generated by an INSERT statement.
Option B: LATEST_INSERT_ID() This option is incorrect. There is no function called LATEST_INSERT_ID() in MySQL.
Option C: INITIAL_INSERT_ID() This option is incorrect. There is no function called INITIAL_INSERT_ID() in MySQL. This function would be useful if you want to know what the initial value of the sequence number was.
Option D: INSERT_ID() This option is also correct. It's another built-in function that does the same thing as LAST_INSERT_ID(). They both return the latest auto-generated sequence number.
So, the best answer is Option A: LAST_INSERT_ID() or Option D: INSERT_ID(). They are essentially the same function. Remember that the value these functions return is specific to your current connection to the MySQL database.
