Answer 1

Answer:

Option 4, all of the above.

Answer 2

All of above (Option 4).

a character constant is one or more characters enclosed within ' ' single quotes but here "thank you" is not enclosed within single quotes and  "Enter values of P,N,R" This is also not enclosed within single quotes and "23.56E-03" is also not enclosed within single quotes. So no option can be a valid character constant.
