Euh... wut?
Is it me and I'm going blind, but aren't the first and the second answer exactly the same?
The second and the third resultset are just swapped around (and why would you do that?)
Why put the third resultset before the second resultset in 3 of the 4 answers?
And the explanation doesn't mention why inserting NULL in another string doesn't result in NULL, but in an empty space instead.
But thanks for the effort

Thanks for the question. interesting to know the null is treated differently in the function.
In regards to answer A and B being the same, I think it's because of copy and paste and forgetting to swap the numbering. I decided to go for the order as it appears and got it right

I am curious: bol does not mention the case the last parameter is NULL. Maybe a BUG?

That's what got me.
Surely it's a bug?
select 'Vinay, ' + NULL + ', Amit'
returns NULL, so I'd have thought
select STUFF('Vinay, Vijay, Amit',8,5,NULL)
should do the same?

It might be
Or just some lazy documentation writers at BOL

My thoughts exactly. I just went for the answers that were in the correct order.
