Let the ten's digit be x and unit's digit be y.
then, (10x+y)-(10y+x)=9
10x+y-10y-x=9
9(x-y)=9
x-y=1
so, all the options given are correct

Maths Quotes

There is something I don't understand about algebra: It has been around for thousands of years, yet no one has ever found out what the value of "x" or "y" really is.

Richard van der Merwe

Sometimes it is useful to know how large your zero is.
