Answer 1

Correct Answer - Option 2 : CTRL + A

The Correct Answer is CTRL + A.

• In a graphical user environment, the keyboard shortcut Ctrl+A is most commonly used to select all text, files, pictures, or other objects. 
• A Control key is a key that is used in computers.
  • Ctrl is a modifier key that performs a special operation when pressed in combination with another key (for example, Ctrl+C), unlike the Shift key, the Control key seldom performs any action when pressed alone.
• Most keyboards have a Control key on or near the bottom left side (in compliance with the international standard ISO/IEC 9995-2), with many also having a Control key on the bottom right.

• The keyboard shortcut Ctrl+K varies depending on the application being used.
  • Ctrl+K, for example, is used to insert a hyperlink in some applications, and Ctrl+K focuses on the search bar in some browsers.
• The shortcut ALT + F5 is used to refresh the system.
• The shift key is used to change the direction of the cursor.
  • The shift is a keyboard modifier key that helps you to type capital letters and other "upper" characters. On the left and right sides of the row below the home row, there are typically two shift keys.
