The command to move the cursor to the beginning of line in MySQL input editor is?

This question is about using the MySQL command-line interface. It asks you how to move the cursor to the beginning of a line while editing a command.

Think of it like using a word processor, but instead of editing a document, you are editing your SQL commands.

The correct answer is Option A: Ctrl-A.

Here's why the other options are incorrect:

* Option B: Ctrl-E This moves the cursor to the end of the line.
* Option C: Ctrl-D This deletes the character to the right of the cursor.
* Option D: Esc-a This combination doesn't have a specific function in the MySQL editor.

Remember: The `Ctrl` key is essential for many commands within the MySQL editor, so keep practicing!
