The maximum size in bytes of a row in MySQL is . . . . . . . .

Answer: Option B

This question is about the limits of data you can store in a single row of a MySQL table. Think of a row as a single entry in your database, like a single person's information in a contact list.

MySQL has a limit on how much data can fit in one of these rows. The question asks for the maximum size, meaning the largest possible amount of data.

Let's look at the options:

* Option A: 65534
* Option B: 65535
* Option C: 65536
* Option D: 65537

The correct answer is Option C: 65536. This means that the largest possible row in a MySQL table can hold 65,536 bytes of data.

Think of it like a box – the box can only hold so much stuff. In MySQL, the box is a row, and the "stuff" is the data you store.
