Excellent trick question.
String comparison for
both char & varchar
ignores trailing spaces - even when ANSI_PADDING is ON.

You need the option
Must declare the scalar variable "@Dec".
When running on a Case Sensitive collation.
Once that select statement on line 2 is adjusted then it would work.

I didn't even notice that capital "D"... I promise it wasn't meant to be any kind of case-sensitive trick question!
Maybe a mod could fix that...

Technically speaking, the explanation for the answer is not correct. The explanation given is that SQL server ignores trailing spaces when comparing strings.
But in this example, SQL server isn't comparing strings
at all
. It's comparing integer values (the length of each string.)
The correct explanation is that SQL server ignores trailing spaces when calculating the length of a string.
