The default case sensitivity of database and table names depends on . . . . . . . .

Solution (By Examveda Team)

This question is about how MySQL handles the names of databases and tables. It's asking whether the names are case-sensitive (meaning "myTable" is different from "MyTable") or case-insensitive (meaning they are treated the same).

Here's what you need to know:
* Case sensitivity is how MySQL treats upper and lowercase letters in names.
* SQL mode is a set of settings that influence how MySQL behaves.

The answer is Option B: Server SQL mode. Let's break it down:
* Option A: SQL server is incorrect because MySQL is the SQL server, and the setting is within the server itself.
* Option C: Operating system of machine is incorrect. While the operating system might be case-sensitive or -insensitive, MySQL's behavior is independent of it.
* Option D: Does not depend on anything is incorrect. MySQL's case sensitivity is determined by the SQL mode.

In simpler terms:
Imagine you have a box of toys. The box has rules about how toys are organized (that's like SQL mode). The box's rules could be:
* "All toys are organized by color" (case-insensitive).
* "Toys are organized by color and then by first letter, so all red toys with names starting with 'A' go first" (case-sensitive).

The way MySQL handles database and table names is similar. The SQL mode determines whether names are treated like the first rule (case-insensitive) or the second rule (case-sensitive).
