While naming a file on the computer, if we press the key corresponding to letter A on the keyboard, what process is carried out inside the CPU to display the letter on the screen?

$\text{'}$A$\text{'}$ is directly displayed on monitor from keyboard, without passing through any memory unit.

$\text{'}A\text{'}$ is converted to its ASCII binary code and stored in the memory unit. Then it is converted back to $\text{'}A\text{'}$ for display.

$\text{'}A\text{'}$ is converted to its special characters and stored in the memory unit. Then it is converted back to $\text{'}A\text{'}$ for display.

$\text{'}$A$\text{'}$ is stored as alphabet $\text{'}A\text{'}$ on the memory unit and displayed back.
