3)

UFT-8 takes 1 to 4 bytes to store a character

It depends on the 1st one which will indicate how many bytes UTF_8 will take up

Hence

Answer is 1-4 bytes

Select all the option

4)

ASCII

ASCII format is more easily transferred between hardware systems or even application programs on the same computer.

It is very difficult process for human to read binary files

If a user take a look at sequence of 4 bytes in binary he won't able to figure it out

But same if the person sees some ASCII letter

For .eg

4000000000

It is easy to identify it is a number

Hence ASCII is the correct answer

2)
